Summary:  
This document details the handling and review of classified files related to Lee Harvey Oswald and the assassination of President John F. Kennedy by U.S. intelligence agencies. It outlines the establishment of a Task Force in 1976 to assess the Church Committee’s Final Report (Book V) and evaluate Agency records on Oswald. The Task Force reviewed extensive materials, including radio traffic, correspondence with the Warren Commission, internal documents, and files from the FBI and Department of State. Ancillary files were created for topics like Gilbert Alvarado-Ugarte, Silvia Duran, and Waldemar, which were later included as appendices to Oswald’s 201 file. The document notes that by 1977, the House Select Committee on Assassinations (HSCA) took over some responsibilities, leading to the sequestration of documents in the Agency’s Warrenton Archives. Later efforts in 1981 and 1991 addressed gaps in the collection, with inventories compiled for HSCA requests and additional materials added to ensure completeness. The text also references interactions between agency staff and HSCA members, including evaluations of documents related to Oswald’s activities in Mexico City and CIA communications to the Warren Commission.
