U.S. Government sponsored sites

National Technical Information Service (NTIS) - National Technical Reports Library (NTRL)

The National Technical Information Service is the primary clearinghouse for federal government technical reports. Its National Technical Reports Library (NTRL) database is available free to the public in a limited Quick Search mode (registration required). It provides access to about 800,000 full text reports as well as over two million bibliographic records since 1964. Non-digitized reports must be purchased directly from NTIS and can't be requested via interlibrary loan. Limit of 5 downloads per session.

SciTech Connect - U.S. Department of Energy

TRAIL-Technical Report Archive and Image Library - TRAIL identifies, acquires, catalogs, and digitizes technical reports issued primarily prior to 1976.

Defense Technical Information Center (DTIC)

DTIC Technical Report collection includes all unclassified, unlimited government-sponsored technical report citations since 1974. Some reports are available in full text online. The scope of DTIC collection includes areas normally associated with Department of Defense research; however, since DoD interests are widespread, the collection also contains information relating to hard sciences, such as biological and medical sciences; environmental pollution and control; and the behavioral and social sciences. 

NASA Technical Reports Server

NASA Technical Reports Server (NTRS) provides access to aerospace-related citations, full-text online documents, and images and videos. The types of information include: conference papers, journal articles, meeting papers, patents, research reports, images, movies, and technical videos – scientific and technical information (STI) created or funded by NASA.

Jet Propulsion Laboratory - NASA Technical Reports Server

National Institute of Standards and Technology (NIST)

Founded in 1901 and now part of the U.S. Department of Commerce, NIST is one of the nation's oldest physical science laboratories. NIST measurements support the smallest of technologies - nanoscale devices so tiny that tens of thousands can fit on the end of a single human hair—to the largest and most complex of human-made creations, from earthquake-resistant skyscrapers to wide-body jetliners to global communication networks.


NEPIS is the U.S. Environmental Protection Agency National Environmental Publications Internet Site. Search, view and print from a collection of more than 6,000 technical and public information documents. 

Los Alamos National Laboratory - The Research Library holds about 1.5 million unclassified technical reports, in paper, microfiche and electronic formats.

TRID is an integrated database that combines the records from TRB’s Transportation Research Information Services (TRIS) Database and the OECD’s Joint Transport Research Centre’s International Transport Research Documentation (ITRD) Database. TRID provides access to more than one million records of transportation research worldwide.

What are Technical Reports?

Technical reports describe the progress or results of scientific or technical research and development. These may include national or international reports by university departments, institutes, private industry or government agencies and laboratories. Issuing (funding) agencies may or may not make reports publicly available and some charge for copies of their reports. 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 usually include the following elements:

  • agency, society, or company delineator
  • year code
  • specific number for each report

Some examples of numbers are:

  • NASA-TM-111279
  • EPA/456/R-99/002
  • SAE 2001-1096

NOTE: Contact the Engineering Library if you need information about finding and obtaining technical reports.
