Technical or scientific reports describe the progress or results of scientific or technical research and development. They are often published by government agencies. Publication and dissemination of technical reports has never been centrally coordinated; therefore, they can be particularly difficult to identify and locate. Technical reports usually appear as part of a numbered series from the issuing agency. These numbers are important and are often the easiest way to find a specific report or document. Each agency has its own numbering system, however technical report number systems follow some common forms.

Defense Technical Information Center (DTIC)
DTIC reports to the Assistant Secretary of Defense For Research and Engineering ASD(RE). Their mission is to provide essential, technical research, development, testing and evaluation (RDT&E) information rapidly, accurately and reliably to support US Department of Defense (DoD).
Science, technology, engineering research and data collections from the US Department of Energy (DOE). Registered users see material details, including calculations for band structure, density of states, x-ray diffraction, elasticity, and user-submitted calculated and experimental data. Registration is free.
Technical reports by The Berkeley Department of Electrical Engineering and Computer Sciences that document work in progress, early versions of results that are eventually published in more traditional media, and supplemental information such as long proofs, software documentation, code listings, or elaborated examples.
It includes the NACA collection, the NASA collection, and the NASA Image eXchange. Over 500,000 aerospace-related citations, over 200,000 full-text online documents, and over 500,000 images and videos are available through a common interface.
Includes 400 Series (Air and Radiation, OAR), 500 Series (Solid Waste and Emergency Response, OSWER), 600 Series (Research and Development, ORB), 700 Series (Prevention, Pesticides and Toxic Substances, OPPTS) and 800 Series (Water, OW) and more.
