According to
the Defense Technical Information Center (DTIC):

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.

than 50 percent of the research records in the collection are available through
the access controlled R&E Gateway, which is accessible to DoD personnel,
defense contractors, federal government personnel and contractors, and selected
academic institutions. The R&E Gateway sites require common access card
(CAC) login or registration.

also provide the general public and industry with access to unclassified,
unlimited information, including many full-text downloadable documents.

In 2009, the
DTIC did a full document inventory. The result, was a more than 10,000 page
document detailing each “accession number” that is assigned to every document
in their collection.

Although it
lacks identifying information on the accession, it gives an indication on what
is currently in the inventory, and which are missing (which was what my
original request was for.)  I have asked DTIC for a bit more information
on the codes, which I will add hear when they respond. For now, here is the
