Examining 23,950 Declassified FBI and CIA Documents from the 2017–2018 JFK Assassination Records Release

The National Archives holds 23,950 individual files in its 2017 2018 JFK release. Most researchers focus on a handful of famous memos, ignoring the macro-level story told by the metadata. We are looking at the raw document logs to see exactly who generated this intelligence, when they wrote it, and what it reveals about the federal government's decades-long investigation.

Bottom line: The 2017 and 2018 JFK release is dominated by FBI and CIA paperwork spanning from 1958 to 1998, proving that federal intelligence gathering related to the assassination continued actively for more than 30 years after Dallas.

Here is what the actual records show when you strip away the speculation and look strictly at the routing slips, dates, and originators.

The Scope of the JFK Assassination Records NARA Collection

The sheer volume of the NARA declassification effort is staggering. Processing nearly 24,000 files required coordinating releases across multiple intelligence and law enforcement agencies. These historical government documents aren't just a snapshot of November 1963.

They represent a massive, ongoing bureaucratic effort to track domestic and international targets. The National Archives declassified files in distinct batches, with major data drops occurring in late 2017 and early 2018.

Here's the thing: the metadata attached to these files is just as revealing as the text inside them. By tracking the "From" and "To" fields, we can map exactly which field offices were driving the intelligence gathering.

FBI's Extensive Involvement in JFK Investigations

The FBI generated the lion's share of the domestic intelligence in this collection. Their paperwork reveals a highly active network of Special Agents in Charge (SAC) communicating constantly with the Director's office in Washington.

Consider 124-10297-10275 (archives.gov PDF), a textual document routed from FBI Headquarters to the Chicago field office on October 4, 1962. This predates the assassination by more than a year. It demonstrates how field offices were already tracking individuals who would later be swept up in the Warren Commission's dragnet.

The Bureau's involvement didn't stop in the 1960s. Document 124-10377-10473 (archives.gov PDF) was routed from FBI Headquarters to New York on April 15, 1998. The investigation's administrative tail stretched for decades.

Key FBI Documents from the 2017–2018 Release

When you pull a sample of FBI CIA declassified documents, the Bureau's internal routing becomes clear. Below is a cross-section of FBI files showing the geographic and chronological spread of their reporting.

Document Title	Originator	Routing	Date	Source File
124-10202-10148	FBI	SAC, CG to DIRECTOR	07/26/1962	(archives.gov PDF)
124-10282-10049	FBI	SAC, PG to DIRECTOR	06/06/1961	(archives.gov PDF)
124-10375-10378	FBI	WMFO to HQ	12/21/1993	(archives.gov PDF)
124-10029-10434	FBI	LEG, OT to DIRECTOR	08/20/1968	(archives.gov PDF)
124-90122-10198	FBI	MM (Miami)	12/02/1964	(archives.gov PDF)

The routing codes are specific. "CG" stands for Chicago, "PG" for Pittsburgh, "MM" for Miami, and "WMFO" for the Washington Metropolitan Field Office. The Bureau was pulling data from across the eastern seaboard and the midwest to feed the central investigation.

They also shared intelligence across agencies. Document 124-10367-10020 (archives.gov PDF) from November 1962 shows FBI Headquarters referring a file directly to NASA.

CIA Records and International Context in the JFK Files

While the FBI handled domestic surveillance, the CIA files in this collection expose the international dimensions of the era. The Agency was highly focused on Latin America, the Caribbean, and foreign consulates.

A prime example is 104-10102-10145 — PERSONAL INFORMATION TAKEN FROM SILVIA TIRADO BOZAN DE DURAN (archives.gov PDF). Dated November 28, 1963—just six days after the assassination—this file targets Duran, a Mexican citizen who worked at the Cuban consulate in Mexico City. She was a critical person of interest because Lee Harvey Oswald visited that consulate in late September 1963 seeking a transit visa to Cuba.

But the CIA files aren't strictly limited to Oswald's direct contacts. They capture the broader geopolitical instability of the 1960s.

Look at 104-10172-10030 (archives.gov PDF). This June 1965 cable from the JMWAVE station (the CIA's secret facility in Miami) to the Director warns of the "possible imminent departure of a 6-man commando team from Florida to the Dominican Republic to assist General Antonio Imbert Barreras."

The result? The JFK archive doubles as a master record of CIA paramilitary and surveillance operations in the Western Hemisphere during the Cold War.

Chronological Breadth of the Declassified Documents

A common misconception is that JFK assassination records only cover 1963 and 1964. The metadata proves otherwise. The government was building files on key figures long before the shooting, and they continued managing the fallout for decades.

Truth is: the timeline of these documents is vast. Breaking down the dates reveals four distinct eras of intelligence gathering.

• Pre-Assassination Surveillance (1950s–1962): Files like 124-10285-10144 (archives.gov PDF) date back to August 29, 1958. The FBI was already monitoring subversive groups and individuals who would later become relevant to the assassination probe.
• The Immediate Aftermath (1963–1964): This is the densest period of reporting. Documents like 124-10305-10004 (archives.gov PDF) from November 1964 show the Miami field office actively feeding data to the Director as the Warren Commission wrapped up.
• The HSCA Era (Late 1970s): Congress reopened the investigation, generating a new wave of inter-agency memos and file reviews.
• The Modern Review Period (1990s): Driven by the JFK Records Act of 1992, agencies began auditing their own files. Document 124-10193-10031 (archives.gov PDF) is a 35-page report routed to D.E. Stukey II on January 23, 1990.

Insights from HSCA Contributions to the JFK Archive

In 1976, the House Select Committee on Assassinations (HSCA) was formed to investigate the deaths of JFK and Martin Luther King Jr. Their work forced federal agencies to dig back into their archives and produce raw files for congressional review.

Many HSCA documents in the collection are undated notes or raw textual files pulled from CIA boxes. For example, 180-10142-10080 (archives.gov PDF) is simply categorized as "NOTES" originating from the CIA, pulled from "Box 12."

Similarly, 180-10142-10056 (archives.gov PDF) is a textual document from "Box 11." These files lack the formal routing slips of FBI memos because they were working materials used by committee investigators.

Other agencies were also pulled into the HSCA's orbit. Document 144-10001-10185 — Blakey request… (archives.gov PDF) is a July 1978 memo from the NSA directly to the HSCA. G. Robert Blakey was the chief counsel for the committee, and this file shows the NSA responding to his specific intelligence requests.

Beyond 2018: What Random Sampling Reveals

The declassification process didn't end in 2018. Subsequent releases, including the 2022 JFK release, continue to surface highly specific operational records. Pulling random samples from across these batches shows the granularity of the intelligence.

Take 104-10247-10115 — MEMO: AMWHIP/1 MEETING WITH AMBIDDY (archives.gov PDF). This January 1965 document details a meeting in New York City involving CIA assets. The use of cryptonyms like AMWHIP and AMBIDDY highlights the Agency's compartmentalized tracking of anti-Castro Cuban exiles.

Even public FOIA requests became part of the permanent record. Document 104-10425-10005 (archives.gov PDF) is a June 1975 priority handling request regarding Claude V. D'Unger. The CIA logged and preserved the administrative friction of citizens trying to pry these files loose.

The FBI was equally meticulous. Document 124-10198-10181 (archives.gov PDF) from January 1967 shows the New York SAC reporting directly to the FBI Director years after the Warren Report was published.

The Bureau never truly closed the book on the surrounding intelligence environment. Document 124-10226-10384 (archives.gov PDF) from June 1961 and 124-10210-10340 (archives.gov PDF) from July 1961 prove that the Chicago field office was a major hub for domestic intelligence gathering during the Kennedy administration.

Quick Takeaways

• Massive Scale: The 2017–2018 NARA release contains 23,950 documents, forming one of the largest single declassification events in U.S. history.
• Early Surveillance: FBI files in the collection date back to at least 1958, proving that federal agencies were tracking key figures long before the assassination.
• Long-Tail Administration: Documents generated as late as 1998 show the FBI was still processing files and managing the administrative fallout of the investigation 35 years later.
• Global Reach: CIA cables from stations like JMWAVE in Miami reveal that the JFK files are inextricably linked to Cold War operations in Cuba and the Dominican Republic.
