According to
the Defense Technical Information Center (DTIC), this is their mission

Defense Technical Information Center (DTIC) has served the information needs of
the Defense community for more than 70 years. DTIC reports to the Assistant
Secretary of Defense For Research and Engineering ASD(RE).

mission is to provide essential, technical research, development, testing and evaluation
(RDT&E) information rapidly, accurately and reliably to support our DoD
customers’ needs.

Under the
Freedom of Information Act (FOIA), you are able to request “report
bibliographies” – a listing of all reports that DTIC has in their system, which
pertain to a certain keyword.

You can also
request searches of other fields, like author, subject, abstract or even the
current classification.

In July of
2016, I requested a list of all documents within DTIC databases, that were
still marked as classified, and dated 1952 or earlier.
