The Assassination Archives and Research Center Library (AARC)"The Assassination Archives and Research Center is the largest private archives in the world which is dedicated to acquiring, preserving, and disseminating information on political assassinations. It includes more than 35,000 pages of scanned documents. Most of these relate to the 1963 assassination of President Kennedy, and include a mixture of long-published reports and newly declassified transcripts and other documents. Also contained in the Public Library are the reports of the Church Committee and the Rockefeller Commission, which in the 1970s studied abuses of the intelligence agencies. The collection also contains relevant material from federal agencies such as the FBI and CIA. Reports, transcripts, and other documents are constantly being added to the AARC Public Library."
