Among the vast files of the HSCA are four boxes of Executive Session files, containing a few dozen transcripts and related materials. These are all reproduced here in chronological order. The first of these come from the early days of the HSCA, when Richard Sprague was Chief Counsel, before his resignation and replacement by G. Robert Blakey.

The Committee also took a great deal of testimony in Executive Session, and very little of that material is contained in this set, which is mostly working discussions of the Committee (these depositions are found in other files of the HSCA, including the "Security Classified testimony" boxes and the voluminous "numbered files."
