Government Reports, Numbering and Coding
Almost all government records and reports have numbers or codes of some kind, the meaning of which are often hard to decipher, and there are dozens of such codes and numbers. For example, the report, "Testing for Extrasensory Perception with a Machine" by E.F. Dagle and J. Mott-Smith, and produced by the Air Force Cambridge Research Labs, May, 1963 had the number: AD-414809. The AD is used by several government agencies, not just the AFCRL.
To help decipher these codes, a book of value is:
Criss-Cross Directory of NASA "N" Numbers and DOD "AD" numbers, 1962-1978. Chicago, IL: SLA-Aerospace Division, 1984. 449 pages. Apparently it is possible to trace from AD to N; from NASA TT or TN to N, etc. There may be subsequent books that do this for pre-1962 and post-1978 government reports.
Lists of Government Reports, Papers, etc.:
There are several sources that list government reports produced by the various government agencies:

1. What are the titles of the files that NARA has that are still classified that are from pre-1947 years? They just released 700 classified FBI files on Hitler in 2014. How many other files are there on Hitler still classified, and how many other files on other subjects are still classified from the pre-1947 years?
