Taping System History

A detailed history of the Nixon White House Tapes from their installation in 1971 to when the National Archives took possession in 1977.

On February 16, 1971 the United States Secret Service (USSS), at the request of President Nixon, installed recording devices in the White House. The first devices were installed in the Oval Office and the Cabinet Room. Over the course of the next 16 months new locations were added including: the president’s office in the Executive Office Building (EOB), telephones in the Oval Office, EOB office, and the Lincoln Sitting Room. Finally, recording devices were setup at Camp David including the president’s study in Aspen Lodge, and telephones on the president’s desk and study table.

President Nixon was not the first president to record private conversations in the White House. President Roosevelt, Truman, and Eisenhower experimented with recording select meetings and press briefings. However, Kennedy was the first president to extensively record meetings and Johnson continued that practice expanding the scope of recordings. During the 1969 transition Nixon learned that Johnson had recording equipment installed in the White House to record meetings and telephone conversations. According to the president’s Chief of Staff, H. R. Haldeman, Nixon “abhorred” the idea of recording conversations and he had the equipment immediately removed after the inauguration. However, over the next few years Nixon changed his mind about a recording system in response to a number of challenges in fully documenting his presidency with the accuracy he desired.

Nixon was concerned that his meetings were not always reported accurately by participants and he wanted to ensure his private discussions were not misconstrued publicly to the benefit of others during his administration. Haldeman theorized, this may have been due to an individual’s lack of familiarity with the topics discussed but he also believed it was a way for those participants to bolster their own image. Another challenge was documenting presidential meetings with foreign leaders. Nixon preferred meeting with foreign dignitaries using only their interpreter. Nixon thought this lent an air of intimacy to the proceedings, which he believed furthered diplomatic discussions, it also presented a problem of ensuring the translations were accurate. At times, Nixon used a National Security Council (NSC) staff member, who understood the language, but did not attend as a translator. This practice, however, was not consistently followed and it still left gaps in the record. A complete record of his presidency, in order to aid in writing his memoir, was the objective and these methods all fell short.

The Nixon administration tried a number of solutions to keep an accurate record of conversations and meetings. In 1969 and 1970 such efforts included note-takers in meetings or the president taking notes himself, debriefing the president after meetings, and having a note-taker outside the Oval Office catching participants leaving to record their thoughts. Nixon rejected these solutions which he felt were intrusive and did not capture the nuances and details of the conversations. As a last resort, the administration sought to enlist Lt. General Vernon Walters, deputy director of the Central Intelligence Agency (CIA), known for his phenomenal memory, to work for the White House as President Nixon’s personal note-taker. However, General Walters bristled at the idea of being anyone’s note-taker.

Two years into his presidency, Nixon, had still not discovered a solution for documenting meetings. It is unclear who reinitiated discussions about a recording system, however, according to Haldeman, Johnson had a conversation with a friend of Nixon’s regarding the benefits of a taping system while ostensibly discussing the process of setting up a presidential library. Johnson mentioned how helpful the recordings were in preparing his memoirs and how the Nixon Administration was mistaken in dismantling the system. Haldeman discussed the idea of recording his meetings with Nixon who subsequently agreed to set up a recording system in the White House. The challenge was to create a system that was low-maintenance and did not require much of the president––who was not comfortable with technology. Nixon settled on a voice-activated system unlike those of his predecessors. Haldeman believed the president would forget to activate the system when he wanted to record, therefore, the voice activation would ensure that the totality of conversations would be captured. The Secret Service maintained the system and would be responsible for replacing tapes and turning the systems on and off based on the location of the president. Haldeman’s assistants Lawrence M. Higby and Alexander P. Butterfield worked with the Secret Service to install the system.

The recording system went live on February 16, 1971 in the Cabinet Room and the Oval Office. The first set of microphones were placed in the Oval Office––five in the president’s desk and one on each side of the fireplace; and two in the Cabinet Room under the table near the president’s chair. On April 6, the president’s EOB office––four microphones in his desk––and telephones in the Oval Office and the Lincoln Sitting Room were added to the system. Finally, the president’s office and two telephones in Aspen Lodge at Camp David began recording on May 18, 1972. Although Nixon was initially reluctant to record his conversations, once the system was in place he wanted a complete record of conversations which far exceeded anything his predecessors had done. What followed was an almost complete record of the president’s daily conversations until the system was shut down in July 1973.

Of utmost importance for the recording system was something that was hands-off for the president who was not tech-savvy. It also needed to be low maintenance for the Secret Service. Alexander Butterfield tasked Alfred Wong, head of Technical Services Division of the Secret Service, to install a system that met these requirements. The taping system was tied into the Secret Service’s presidential locator system. When the president entered a recording area the presidential locator was updated and an agent would set the recorder switch to the record/pause mode. Whenever the voice operated relay microphones detected sound the machines began recording. The machines would continue to record as long as sound was detected and when it became quiet the machines would return to record/pause after 20-30 seconds.

Notably, the Cabinet Room is the only room that was not automatically turned-on with voice activation. While there were on/off switches installed near the president’s place on the Cabinet Room table he in all likelihood never used them. There was another switch installed near Butterfield’s desk and the responsibility for turning this system on and off fell to Butterfield. Often they were left on long after meetings concluded, capturing various sounds including tours, cleaning, and the daily bustle of the White House.

Similarly, when the president entered the Oval Office, the EOB, or his Aspen Lodge study he triggered the activation of the recording machines. Often, when the president was in those rooms, even if he was not speaking, the machines continued, because of ambient noises, television, music, and other noises. These segments are known as room noise and while they are not released to the public archivists review the content to ensure there is no conversation or withdrawn material on them. See processing notes for more information on room noise.

All of the recording stations were equipped with two Sony 800B recorders loaded with extremely thin 0.5mm tape. The recorders had a timer affixed to them that switched which recorder was active every twenty-four hours. During the weekend one recorder remained active for forty-eight hours. In order to keep maintenance low, the recorders operated at the slowest speed, 15/16, which allowed for up to six and a half hours of record time per reel. The quality of tape stock varied and the Sony machines and microphones were not made for recording conversations. All of these conditions have led to the original tapes––and all subsequent copies––to be of generally poor quality which makes listening a challenge.

Before Nixon all presidential records were the personal property of the president. After an administration was over the president was allowed to retain legal custody of their records. Presidents would often use their papers to write their memoirs and when finished, traditionally gave their papers back to the American people in the form of a deed of gift. Nixon, therefore, was confident in the precedent that his recordings and papers would remain in his custody like the presidents who proceeded him.

That all changed on Friday July 13, 1973 when in a private interrogation with committee investigators Alexander P. Butterfield revealed the existence of a taping system in the White House. He believed he was just corroborating information that the committee already knew. During his public testimony, three days later on July 16, before the Senate Select Committee on Presidential Campaign Activities––also known as the Ervin Committee after the committees chairman Samuel Ervin––Butterfield revealed to the nation the existence of the White House Tapes. This was the final day the tapes were operational. The Camp David recordings had been completely shut down by late June but after Butterfield’s testimony the remaining recorders were also shut down.

This revelation opened a new avenue in both the Senate investigation and the Special Prosecutor’s investigation. The recordings could help prove the validity of John W. Dean, III’s explosive allegations, before the committee on June 25, 1973, regarding the Nixon Administration or they could bolster the administration’s side of the story. New avenues of investigation also meant new avenues of litigation and obstruction as the Nixon Administration attempted to prevent the release of any tapes. Immediately after Butterfield’s testimony, Nixon directed Secret Service agents not to give testimony regarding their duties. On July 23 the committee voted unanimously to subpoena the tapes which required the president to deliver them to the committee. The Special Prosecutor Archibald Cox requested tapes and after being rebuffed by the administration secured a subpoena.

On July 25 Nixon informed District Court Judge John Sirica he would not comply with Cox’s subpoena citing precedents which showed that presidents could not be “subjected to compulsory process from the courts.” The next day President Nixon wrote to Senator Ervin denying the committee access to the tapes citing executive privilege and separation of powers. Vice Chairman Howard Baker, a Tennessee Republican, suggested suing the President. On August 9 the committee sued the president in federal court. The case was dismissed due to a lack of jurisdiction and that decision was upheld upon appeal. The country now faced a full-blown constitutional crisis.

The Special Prosecutor and the president’s lawyer, Charles Alan Wright, met in court on August 22. Judge Sirica eventually sided with the Special Prosecutor and the administration appealed the decision stating they would only comply with a decision from the highest court in the land. On October 12, the Circuit Court of Appeals ruled in favor of the Special Prosecutor concluding that the president should turn the tapes over to Judge Sirica. They stated that the president was not above the law but also pleaded with both sides to make an out-of-court settlement. Nixon’s conundrum was to find a way to comply with the order without incriminating himself.

Nixon proposed a compromise to create transcripts of the relevant tapes, give them to the Judge Sirica, and then subsequently fire Cox. Attorney General Elliot Richardson informed the president he would resign if that happened. The president’s new Chief of Staff, Alexander M. Haig, proposed the idea of using John C. Stennis to verify the president’s transcripts. Stennis, although well-respected, was 72 and had long been battling a serious illness. Only recently had he come back to the Senate. It was also well-known that Stennis was hard of hearing. The administration portrayed this as an acceptable method to allow access to the tapes while redacting personal details or national security information before it was submitted to the court. They believed that the only relevant sections of the tapes were those dealing directly with the investigation and wanted to use a broad national security brush to redact segments that were unfavorable to them.

On October 16, the Nixon Administration proposed using a third-party to verify the president’s transcripts. Two days later, Cox rejected the compromise citing he could not rely on a unilateral determination of the evidence. Furthermore, the Nixon Administration only wanted to allow the Special Prosecutor to receive tapes regarding the break-in and cover-up, and Cox wanted tapes that were relevant to other areas of interest in the investigation. On October 20 Nixon ordered Richardson to fire the Special Prosecutor. Richardson resigned, and then the Assistant Attorney General William Ruckelshaus also resigned rather than carry out the order. The third-in-command Solicitor General Robert Bork agreed to carry out the order. This series of events, known as the Saturday Night Massacre, may have delayed the release of the tapes for a time, but the event ensured they would eventually be released.

The firing of Cox on October 20 led to a firestorm of disapproval in Congress and around the country. In November Leon Jaworski accepted the position of Special Prosecutor and with the backing of a more confrontational Senate, he had more independence and protection than his predecessor. Soon afterwards the Special Prosecutor was informed that two tapes requested were missing and that the tape for June 20, 1972 had an 18 ½ minute gap. The Nixon Administration stated the erasure was accidental, and the president’s personal secretary, Rose Mary Woods, claimed she had inadvertently erased that portion of tape. On November 26 lawyers for the president released seven tapes to Judge Sirica and after listening to the tapes Sirica released a portion of them to Jaworski on December 21. Those tape segments proved helpful in corroborating the case against the administration. The grand jury indicted a number of the president’s aides, and in May, Haig was informed by Jaworski, that the president had been named as an unindicted co-conspirator.

On April 16, 1974 Jaworski issued a subpoena asking for sixty-four additional tapes. The president once again opposed the subpoena in court, citing executive privilege and separation of powers. Judge Sirica ruled against the president on May 20 which gave the administration until the May 31 to comply or appeal. The president appealed and Jaworski asked the Supreme Court to take immediate jurisdiction. On July 8 the Special Prosecutor and the president’s lawyer, James St. Clair, presented their arguments before the Supreme Court. United States v. Nixon was an unanimous 8-0 decision; Associate Justice William Rehnquist recused himself, against the president. Handed down on July 24 the decision effectively ended the presidency of Richard Nixon and allowed the Special Prosecutor access to all the tapes that were subpoenaed––including the June 23, 1972 tape which contained the “smoking gun” conversation.

Richard Nixon resigned on August 9 and within one month the former president signed an agreement with the Administrator for the General Services, Arthur F. Sampson. This contract, the Nixon-Sampson Agreement, covered all the tapes and documents of the Nixon presidency. It stipulated that the government would keep all materials in a federal facility behind a two-key system. Access would require the approval of both Nixon and the administrator (or their proxies). Nixon could access the materials for judicial cases and the tapes would become government property on September 1, 1979. However, Nixon reserved the right to order their destruction at any time. Furthermore, the agreement required the tapes to be destroyed on September 1, 1984 or upon Nixon’s death, whichever happened first. Lawsuits sprang up immediately seeking to void this agreement. Congress stepped in and passed the Presidential Recordings and Materials Preservation Act (PRMPA). On December 19, 1974, President Gerald R. Ford signed PRMPA.

PRMPA stated that the Archivist of the United States shall retain complete possession and control of original recordings, as well as all papers, documents, other materials created during the Nixon administration that had historical or commemorative value. The act allowed for access to the materials by former President Nixon and the Watergate Special Prosecution Force, as well as for the purpose of legal discovery and ongoing governmental business. Section 104 of PRMPA mandated that the General Services Administration (GSA), of which NARA was originally part of as the National Archives Records Service (NARS), submit to each house of Congress a set of proposed regulations describing procedures for processing and providing public access to the Nixon Presidential materials in its possession. Section 105 of PRMPA provided the Federal Court for the District of Columbia (DDC) with exclusive jurisdiction to hear cases challenging the legal or constitutional validity of the act or implementing regulations. DDC also retained jurisdiction to settle disputes involving custody and control over the materials or compensation resulting from the seizure of the materials.

The US Supreme Court upheld the constitutionality of PRMPA in Nixon v. Administrator of General Services. The Supreme Court's decision on June 28, 1977, allowed the National Archives to take possession of the Nixon Presidential materials. In a memorandum signed on July 29, 1977, by Counsel to the President Robert J. Lipshutz and GSA Administrator Jay Solomon, the White House Office of Counsel formally transferred custody and control over the Nixon Presidential materials to the National Archives. On August 9, 1977, sensitive Presidential materials, including Haldeman's Diary, were transferred from the EOB to a vault within the National Archives.

Soon after the Supreme Court handed down its decision, GSA submitted a set of implementing regulations to Congress which was approved on December 26, 1977, and became effective on January 16, 1978. The fourth set of implementing regulations refined the meaning of presidential historical materials to include materials made or received by the president and his staff in fulfilling their constitutional and statutory duties of the Office of the President. The regulations further distinguished presidential materials from private or personal materials which relate only to an individual's family or non-public affairs. The implementing regulations also stipulated that the National Archives must prioritize the identification and segregation of personal materials interfiled with presidential materials, and return any personal materials to their owner in a timely manner. With formalized definitions of presidential and personal materials in place, a distinction could now be made under PRMPA between materials for retention by archivists and others that must be returned to individuals.

Finding Aids

Each tape has a Tape Subject Log as the archival finding aid. A log indicates each conversation, the date, time, location, participants, and includes action statement in particular highlighting participants movements. Each conversation on a tape then has an hierarchical outline of topics discussed in the conversation. Any withdrawal within a conversation will be identified at the point where it occurs.

Archival and Processing History

A processing history of the Nixon White House Tapes from 1978 through the present.

The National Archives and Records Administration (NARA) took physical possession of the White House Tapes in August of 1977. From March through April of 1978, NARA’s primary focus was on creating a preservation copy of the original tapes. The original tapes were .5 mil and 6 ½ hours long and they were recorded at the very slow speed 15/16 inches per second (ips). NARA staff rewound the original tapes onto larger seven inch reel with a four inch hub which provided a tighter, more even wind. The preservation duplicate was on 1.0 mil tape and it was recorded at 3 ¾ ips. This copy is known as the “S-Copy”. However, because of ongoing legal disputes, at this time, NARA was not permitted to listen to the tapes and instead had to complete the duplication process by monitoring signal levels on the machines.

By September 1978, NARA had finished the duplication and started to processes the tapes in order to gain intellectual control over the collection. The original tape boxes had very little information about the content of the tapes and usually only included an approximate date of creation. Archivists listened to the tapes to start piecing together participants, subjects, date, location etcetera. This process also included a review of the content to identify restricted sections of each conversation in accordance with PRMPA, and its implementing public access regulations––which is more fully described below. During this period the existence of seven blank reels of tape was discovered: 171, 173, 175, 187, 600, 680, and 950. These reels may have been placed on the recorders but were never used. Nonetheless they were given number designations. They are currently arranged as the Blank Sound Recording Series.

Despite gaining more intellectual control over the collection archivists needed a solution for quickly and consistently navigating the tapes to find specific conversations and restrictions in order to comply with PRMPA and the various legal decisions. To solve this problem, NARA created another duplication of the tapes for reference use. This copy, known as the “Enhanced Masters,” had additional technical processing which included spectrum analysis, signal boosting, noise removal, and each tape was stamped with Society of Motion Picture & Television Engineers (SMPTE) timecode. The Enhanced Masters were made on 3 ¾ ips and 1.5 millimeter tape. Each reel was approximately one-hour long with multiple reels making up a full tape. The timecode enabled archivists to fully comply with PRMPA restrictions.

Now that archivists could accurately pinpoint segments of the tapes they began a comprehensive review of the tapes. Under PRMPA, and a subsequent agreement in 1979, NARA was required to return personal and private conversations to the former president. Any conversation where Nixon was not using the constitutional or statutory powers of the office of the Presidency was considered personal. Therefore, conversations with his family and conversations where he was acting as the head of the Republican Party––and speaking purely in his private political role––were to be returned.

All presidential conversations had to be reviewed by NARA under PRMPA guidelines and segments found to have restricted content were separated into their proper PRMPA categories. The PRMPA guidelines define eight restriction categories:

A: Violate a Federal statute or agency policy;

B: Reveal national security information;

C: Violate an individual’s rights (pending);

D: Constitute a clearly unwarranted invasion of personal privacy;

E: Disclose trade secrets or confidential commercial or financial information;

F: Disclose investigatory/law enforcement information;

G: Disclose purely private and personal information, as defined by the PRMPA;

H: Disclose non-historical material.

During this review, NARA was also required by court subpoenas to provide transcriptions for sections of conversations needed in court. (Previously, some transcripts were created by the FBI and the Special Prosecutor during the Watergate investigations.) This process was incredibly time consuming and it was impossible to guarantee 100 percent accuracy, therefore, NARA created detailed subject logs of all conversations except when mandated by the courts to create a transcript. The subject logs described the main conversation topics, sub-topics, participants, entrances and exits by staff, and telephone calls. Paired with the Presidential Daily Diary, archivists were able to add exact time of day or approximate time of day to each room and telephone conversation.

The review process was detailed and comprehensive. Each tape had a processing folder which held all documentation regarding that tape. The tape was then reviewed by two archivists, both of which listened to it in its entirety. During the first review, an archivist created a detailed subject log of the topics and people in the conversation, marked the movement of staff in and out of the office space, and flagged PRMPA restriction categories. To aide in review archivists used a plethora of historical sources––including the Presidential Daily Diary, Public Papers, staff memorandum, and any other pertinent primary and secondary sources––in order to ensure historical context for the conversations. Withdrawal sheets were also created in order to document decisions regarding the PRMPA restrictions. These sheets listed the beginning and ending timecode, the beginning and ending keywords, and the restriction category of the withdrawal. After the completion of this review a second, more senior, archivist re-reviewed the tape to verify the first reviewer’s decisions. After a thorough review the tape was passed on to Archives Specialists for editing.

Upon receiving the reviewed tape, Archives Specialists used the reviewer’s decisions to physically delete the restricted content from the tape and splice in 10 seconds of blank leader tape. These blank leaders were marked with the tape, conversation, and withdrawal number. Similarly, blank leader tape was spliced onto the restricted tape sections with the identifying information and all of these were spliced together into a large reel based on PRMPA restriction category. This method allowed for any withdrawal to be easily found and reinserted back into a conversation when appropriate. All of these changes were made to the “Enhanced Masters” and the “S-Copy” remained untouched.

In the late 1980’s a dispute arose between the Nixon and NARA. After releasing twelve-hours of conversations and transcripts created by the Watergate Special Prosecution Force (WSPF), which were played in court during the Watergate trials, NARA prepared to release the rest of the subpoenaed tapes, however, the former president sought to block their release. The release of these tapes was delayed until 1991. This delay was also coupled with a decision by the NARA to re-review all the tapes. This controversial decision led to a large turnover in staff who disagreed with NARA’s decision to re-review the tapes.

On May 17, 1993 three-hours of Abuse of Governmental Power (AOGP) conversations were released by the NARA. One of the primary directives of PRMPA was “to provide the public with the full truth, at the earliest reasonable date, of the abuses of governmental powers popularly identified under the generic term “Watergate”.” While many of these conversations were identified by the WSPF, many were not, and archivists identified conversations that met this standard based on the criteria which were investigated by the Senate Select Committee on Presidential Campaign Activities 1972. The ten categories were:
1. Misuse of Government Agencies
2. Watergate break-in
3. Watergate cover-up
4. Campaign practices
5. Obstruction of Justice
6. Campaign financing
7. Milk Fund Investigation
8. Hughes-Rebozo Investigation
9. Emoluments and Tax Evasion
10. International Telephone and Telegraph (ITT) Investigation
The AOGP was the final release of this era of tapes review; and with the Nixon’s death in 1994 only sixty-three hours of conversation had been released to the public. Despite PRMPA mandating the speedy review and release of the tapes to the public, Richard Nixon had been able to significantly delay the release of the majority of the tapes for over a decade.

The delay in the release of the tapes led directly to a scheduled release of tape conversations known as the chronological releases. The chronological releases was a result of the long delay and constant legal wrangling between NARA and Nixon spurred a lawsuit from historian Stanley Kutler and the advocacy group Public Citizen. Nixon’s lawyers joined the suit and in 1996 a compromise was reached. The Tapes Settlement Agreement stipulated that 201 hours of AOGP conversations would be quickly released, Cabinet Room conversations would be released next, and then the remaining tapes would be released in five chronological segments, with the fifth segment, being the largest, split into five smaller segments.

The Abuse of Governmental Power conversations were released in three parts on May 17, 1993, November 18, 1996, and February 1999 with 2,224 conversation segments totaling 258 hours from February 1971 through July 1973.

The Cabinet Room Conversations were released to the public in two parts on October 16, 1996 and February 28, 2002 and consisted of 83 tapes with 436 conversations totaling 154 hours from February 1971 through July 1973.

The chronological releases included all tapes from a date range in every location except the Cabinet Room, which were released separately. Furthermore, a process was created for the Nixon estate and other individuals who were recorded to object their release. The only outstanding issue not agreed upon was the Nixon estate’s dispute with NARA’s decision to retain a complete copy of the tapes including the “G” personal returnable segments. The Nixon estate believed those segments should be returned while NARA wanted to retain them until work was completed.

Archivists began reviewing the tapes in accordance with PRMPA regulations and the Tape Settlement Agreement. In addition to the PRMPA categories, archivists also withheld certain portions of conversations that they could not adequately review for release at the time because they were unintelligible. These portions are noted on the tape subject log as “Unintelligible.” For all of the PRMPA withdrawals (except those removed because they were unintelligible), the tape subject log noted the relevant restriction category and the duration of the withdrawal. For national security withdrawals, the tape subject log also indicated the main topic of the withdrawal.

NARA also began another tapes duplication effort in 1993. The “S Copy” had been erased during 1985-86 and the “Enhanced Copy” was beginning to exhibit sticky-shed syndrome. Sticky-shed is when the binder which holds magnetic tape together starts to degrade causing the tape to stick. Baking can counteract sticky-shed for a period of time but archivists decided it was best to create new preservations copies. Four new copies were created including a new preservation analog, the “P-Analog”, on 1.5 mm on ¼ inch open reels at 3.75 ips.

The second and third copies served as the preservation digital copy which was made on Digital Audio Tape (DAT) AMPEX #467 cassette. These are known as the “P-DATs” and from this copy a fourth copy was created, the “Edited DATS or E-DATs” which had the “G” segments erased with a 1 kHz tone. Archivists used the E-DAT to complete the first four chronological releases. All copies of the digital and analog masters were stamped with SMPTE timecode to facilitate archival work. All of the masters had the audio equalized and processed to reduce some of the noise and imperfections in the recordings. Due to the ongoing legal disputes at the time archivists were unable to listen to the “G” segments for more than a few moments to set or check the levels.

The 1st Chronological Release was made public on October 5, 1999 and consisted of 134 tapes with 3,646 conversations totaling 443 hours from February through July 1971.

The 2nd Chronological Release was made public on October 26, 2000 and consisted of 143 tapes with 4,140 conversations totaling 420 hours from August through December 1971.

The 3rd Chronological Release was made public on February 28, 2002 and consisted of 170 tapes with 4,127 conversations totaling 426 hours from January through June 1972.

The 4th Chronological Release was made public on December 10, 2003 and consisted of 154 tapes with 3,073 conversations totaling 238 hours from July through October 1972.

The next chronological releases would not come for another four years. During that time the Nixon Presidential Library, which was not part of the National Archives, became an official Presidential Library on July 11, 2007. As part of this agreement the Nixon Foundation deeded the political portions of the tapes to the federal government. Previously, all political conversations had been classified as “G” personal returnable. Those conversations could now be reviewed and released to the public. The new criteria for personal returnable was the former president’s health, his personal finances, and the private, non-public activities of the First Family (Thelma “Pat” Nixon, Tricia Nixon Cox, Edward Cox, Julie Nixon Eisenhower, and David Eisenhower). Access to the tapes was now governed by the regulations under PRMPA, the 1996 Tapes Settlement Agreement, and the 2007 deed of gift.

Under the 2007 deed of gift agreement, the Nixon Foundation also allowed NARA to retain and release room noise captured on the tapes that had been designated as “G” material under PRMPA. If President Nixon was alone in a room during a room noise recording, the room noise was withdrawn as “G” personal returnable. If President Nixon was not in the room, the room noise was withdrawn as either “G” or as “H” non-historical. Archivists reviewed these room noise segments the same as conversations, however, room noise segments were not released directly to the public, but they are available upon request.

The 5th Chronological release was the first release to include the 2007 deed of gift provisions including the release of the political “G” which had until that point been restricted. Archivists retired the E-DATs and began to use one of the P-DAT copies for review work. At the same time the Nixon Library acquired two SADiE4 Digital Audio Workstations [DAWs]. The DATs were imported into the SADiE system which staff could use to edit and output conversations to CD. Starting in 2007 conversations were simultaneously released online via the Nixon Library website. Now a more thorough record of the presidency could be obtained from the tapes, and the tapes were beginning their shift from analog to digital.

5th Chronological Release Part I was made public July 11, 2007 and consisted of 3 tapes with 165 conversations totaling 11.5 hours from November 1972.

5th Chronological Release Part II was made public on December 2, 2008 and consisted of 55 tapes with 1,398 conversations totaling 198 hours from November 1972 through December 1972.

5th Chronological Release Part III was made public on June 23, 2009 and consisted of 36 tapes with 994 conversations totaling 154 hours from January through February 1973.

5th Chronological Release Part IV was made public on December 9, 2010 and consisted of 75 tapes with 1,801 conversations totaling 265 hours from February through April 1973.

5th Chronological Release Part V was made public on August 21, 2013 and consisted of 94 tapes with 2,905 conversation totaling 340 hours from April through July 12, 1973.

The release on August 21 was the last portion of the tapes that had not been made public. After 35 years of review and multiple legal challenges archivists had finally released all of the Nixon White House Tapes to the public.

Even before the August 21, 2013 release, Nixon Library archivists had begun preparation for the next iteration of the tapes. In 2010 the Nixon Library submitted a proposal for funding to NARA’s Preservation Programs to create a new preservation analog copy of the tapes. Due to the 2007 deed of gift there was a significant portion of “G” conversations that needed to be reviewed and released. In 2011, NARA approved the funding with the caveat that the new preservation copy would be digital, since analog tape have gotten increasingly rare and expensive.

From June 2011 through September 2012, the Nixon Library procured the digital equipment and storage necessary for a project of this magnitude. Two SADiE6 DAWs for preservation mastering; 4 Dell DAWs with WaveLab for digital review, editing, and quality control; and 2 Synology Network Attached Storage (NAS) units were acquired. The goal of the project was to be a complete digital preservation transfer, conforming to NARA preservation standards and practices, of the “P-Analog” copy of the tapes for digital review, editing, and release.

Before archivists began digitally transferring the project, Nixon Library staff undertook a massive data digitization and modernization project in 2013 which included creating a tape dataset in an Excel comma-separated values (CSV) format that contained the following data from every single conversation: identification name, dates, times, participants, recording location, latitude and longitude, description, and other pertinent information. Archivists also took data that was locked in Microsoft Access databases––participant names, conversation subjects, and main topics––reorganized and modernized the data to comply with current archival standards. This data was placed in Excel spreadsheets and was made compatible with Extensible Markup Language (XML) to be used as metadata for digitized tapes. Staff digitized the information from the boxes tapes were housed in which would also be used for metadata and quality control. Furthermore, staff digitized every national security withdrawal into Excel spreadsheets and segregated them by recording location to aid in Mandatory Declassification Review (MDR).

The next stage of the project was the digital transfer of the “P-Analog” tapes. Following the recommendations of NARA’s Preservation Lab, the Nixon Library elected to do a flat transfer of the tapes. As discussed above, during the Chronological Review era all of the tape reels were processed and had signal boosting in order to improve audibility. A flat transfer streamlined the process and was more in keeping with current archival principles. The digital format was an uncompressed stereo Broadcast WAV––as defined by the European Broadcasting Union (EBU)––with a frequency of 96 kHz and 24 bits. The file size was going to be about 2 GB/hour and a full transfer was going to require approximately 14 TB for two preservation copies.

The digital transfer was completed by connecting a Studer to the SADiE6 system, playing the tape, and recording it in real-time into the SADiE6. Each reel was approximately one-hour long and there were anywhere from one to seven reels per tape. Once an entire tape was completed the XML data created earlier was inserted into the tape reels with BWF MetaEdit and then the entire tape was rendered out from the SADiE6 to the Nixon Library servers. From that point on archivists would work in a digital environment and would open the reels in WaveLab to conduct quality control. During the quality control process archivists checked the audio levels, SMPTE timecode levels, metadata, and overall soundness of the digital file. If the file passed quality control MD5 checksums were embedded and two clones of the files were created and placed on different servers. If the file did not pass quality control, it was sent back to be re-digitized to fix the error. The complete digitization of the tapes is scheduled to be completed by Fall 2018.

With the preservation process underway archivists began working to develop the next steps for processing national security information. By 2012 all national security withdrawals had been officially requested through MDR procedures. Archivists used the MDR requests to create a queue for which tapes were to be processed and reviewed first. Archivists needed to simultaneously develop processes for MDR in addition to the tapes review process already in place. Therefore, the Nixon library developed a two-pronged strategy to accommodate both MDR and tape review. In order to process tapes, archivists began another digitization project. This project involved taking analog determination sheets––which document the SMPTE timecode beginning and end of each conversation, room noise, and withdrawals––and digitizing them. These would be used in conjunction with WaveLab to create montages. Montages are like onion skins that archivists can use to modify and markup the tapes without changing the files. To complete a montage an archivist has to digitally splice together each reel to recreate a complete tape––which were broken up into separate one-hour reels during preservation––and then add in markers for conversations, withdrawals, and room noise. After a montage is completed, the tape is then ready to be processed for MDR review.

Next archivists developed a new method for MDR review. The necessary data was digitized, but archivists now needed a way to automatically populate the data in analog sheets. These sheets would be given to the various equity holders to facilitate their review of restricted segments. Furthermore, archivists needed a way for the MDR reviewers to listen to the various segments. To solve the first problem archivists created new MDR review documents, based on the textual model, but with important changes that reflected the audio nature of the collection. Archivists then used mail merge in Microsoft Word to pull from various Excel spreadsheets to automatically populate MDR documents. It was important for archivists to move away from the CD model of the Chronological Review era so that they could harness all the advantages of the digital format. CDs are also expensive, inefficient, and need to be disposed of properly. The Nixon Library decided to invest in five Sony Walkman NW-E390 MP3 players. With these archivists could load playlists for reviewers and they could harness the metadata they had to embed in MP3’s identifying information which would aid MDR reviewers.

With these issues settled archivists began the process of getting every national security withdrawal reviewed. They also had to re-review all the “G” withdrawals from the 1st through the 4th Chronological review. Using the methods developed by their predecessors, archivists began to review the tapes for content. Much of tape review remains the same. A tape is reviewed by two archivists to ensure compliance with PRMPA, the Tapes Settlement Agreement, and the 2007 deed of gift. There are some areas where current tape processing is different however. Previous eras, inserted a 10 sec 1 kHz tone into every withdrawal. Mainly, this was done because of the limited space available on CDs and audiocassettes. With the tapes completely digital archivists edit out the restricted segment and insert in a 1 kHz tone of the same length as the withdrawal. When a tape is finished, each conversation is rendered out separately as a high-quality mono uncompressed Pulse Code Modulation (PCM) Broadcast WAV EBU at 44.1 kHz and 24 bits. Those Broadcast WAVs are then embedded with metadata at the conversation level. The WAVs are then converted into MP3s at 320 kbps, metadata added as needed, and then are posted to the website as the public access copy of the tapes.

Some of the overriding goals of this review of the tapes was to bring all tapes into conformity with the 2007 deed of gift. There are large segments of political conversations that are now going to be available to the public for the first time. Simultaneously, archivists are updating and standardizing the tapes finding aid. The finding aid––which has been created at different times, with different technology, and different standards––needed to be brought up to modern archival standards. This standardization includes language and appearance. One major change is how “unintelligible” withdrawals will now be treated like every other withdrawal on the tape subject logs with identification information and duration. Previously, the logs marked these withdrawals only with [unintelligible] but no other identifiable information or duration. This change will improve transparency between archivists and the public.

Building upon the work of previous archivists to improve both the clarity and consistency of tapes and finding aids was paramount. Previous eras had to contend with reviewing tapes and at the same time potential legal threats. With those threats now removed, archivists had the time to standardize the language and update decision-making processes to more closely align the entire collection with current archival standards. To accomplish this an internal manual was created with detailed work-flows and best practices. Training to review tapes is intensive and archivists seek to form a collaborative atmosphere in order to best interpret the various laws and regulations ensuring compliance with the law and maximum public transparency. With all archivists on the same page there will be a uniformity of purpose and practice that will create a better product for the public.

In the Spring of 2018 the Nixon Library released the first batch of new tapes with the intent to release new tapes in full after review and MDR work is completed. As of September 2018 all 4,042 reels of the Nixon White House Tapes have been digitized.
