# CHAPTER 5: The Standards FOR REVIEW: REVIEW BOARD "COMMON LAW"b. CIA's Lee Harvey Oswald "201" file.CIA opens a 201 file on an individual when it has an "operational interest" in that person. The CIA opened its 201 file on Lee Harvey Oswald in December 1960 when it received a request from the Department of State on defectors. After President Kennedy's assassination, the Oswald 201 file served as a depository for records CIA gathered and created during CIA's wide-ranging investigation of the assassination. Thus, the file provides the most complete record of the CIA's inquiry in the months and years immediately following the assassination.c. The FBI's "House Select Committee on *Assassinations*"(HSCA) Subject Files.During the HSCA's tenure, the Committee made a number of requests to the FBI for records that the Committee believed might be relevant to their investigation of the Kennedy assassination. In response to the HSCA's requests, the FBI made available to the HSCA staff approximately 200,000 pages of FBI files. The FBI began its processing of the "HSCA Subject" files in 1993, The Review Board applied its "Segregated Collection" guidelines (explained below) to the HSCA subject files.d. The CIA's "Segregated Collection" files.HSCA investigators gained access to CIA files. Upon completion of the HSCA's work, the CIA kept separate the files that it had made available to the HSCA and retained them as a segregated collection. This collection is divided into two parts: paper records and microfilm. CIA made 63 boxes of paper records available to the HSCA staff. The paper records consist, in many cases, of particular records that CIA culled from various files. The 64th box of the CIA's segregated collection contains 72 reels of microfilm and represents the entire set of files from which records were made available to the HSCA. Thus, in many cases, the microfilmed files contain material well beyond the scope of the HSCA investigation and may, for example, cover an agent's entire career when only a small portion of it intersected with the assassination story.e. FBI records on the congressional committees that investigated the assassination.The JFK Act defined "assassination record" to include records relating to the Kennedy assassination that were used by the congressional committees who investigated events surrounding the assassination.[^24]Before President Clinton appointed the Review Board, the FBI collected and began to process its administrative files relating to its involvement with each of these committees. In large part, the records contained in the Bureau's administrative files related to topics other than the Kennedy assassination. To the extent that the Review Board found records in these files that concerned topics other than the Kennedy assassination, it designated the records not believed relevant (or "NBR" as that acronym is defined *infra*) and removed them from further consideration.f. Requests for Additional Information.Congress included in the JFK Act a provision that allowed the Review Board to obtain additional information and records beyond those that were reviewed by previous investigations. Chapter 6 of this report explains the requests that the Review Board made and the assassination records designated as a result of those requests.B. DECLASSIFICATION STANDARDSThe Review Board's primary purpose, as outlined in section 7(b) of the JFK Act, was to determine whether an agency's request for postponement of disclosure of an assassination record met the criteria for postponement set forth in section 6. Section 6 consisted of an introductory clause, which established the "clear and convincing evidence" standard, and five subsections that set forth the criteria under which the Review Board could agree to postpone public disclosure of assassination-related information.1.
