The Defense Technical Information Center ( DTIC ) is the premier repository for research and engineering information for the United States Department of Defense . DTIC's Suite of Services is available to DoD personnel, defense contractors, federal government personnel and contractors and selected academic institutions. The general public can access unclassified, unlimited information, including many full-text downloadable documents, through the public Web site, .
DTIC's collections contain over 4 million documents including technical reports, research in progress and Independent Research and Development (IR&D) summaries. DTIC also publishes searchable Congressional budget data shortly after its release from Congress. DTIC acquires approximately 25,000 new documents each year. 
On June 4, 2004, DTIC became a DoD Field Activity under the management of the Under Secretary of Defense for Acquisition, Technology, and Logistics, reporting to the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)). Mr. Christopher Thomas is the Administrator.
DTIC's mission statement is "To provide essential, technical research, development, testing and evaluation (RDT&E) information rapidly, accurately and reliably to support our DoD customers' needs." 
Established in June 1945 as the Air Documents Research Center (ADRC), the agency’s first mission was to collect German air documents. The documents collected were divided into three categories: documents that would assist the war in the Pacific theater, documents of immediate intelligence interest to the United States or British forces and documents of interest for future research.
In 1945, the ADRC moved operations from London, in the United Kingdom , to Wright Field in Dayton, Ohio, under the name Air Documents Division (ADD); the ADD staff cataloged captured documents and translated a small number of reports deemed high-priority research. In 1948, the secretaries of the Navy and Air Force redesigned ADD into the Central Air Documents Office (CADO) giving it the collection of captured documents and also broadened its mission to include collecting, processing and disseminating information for use within military regulations. Since 1948, the organization has evolved—in name and mission—to become the “central resource for DoD- and government-funded scientific, technical, engineering and business related information” for the DoD community.
A summarized version of the history of DTIC is available from the organization. 
1951 —CADO becomes the Armed Services Technical Information Agency (ASTIA).
1962 —The DoD Scientific and Technical Information (STINFO) Program is established.
1963 —ASTIA is renamed Defense Documentation Center (DDC) and becomes a field activity of the Defense Supply Agency (DSA).
1972 —The Defense Research, Development, Test and Evaluation Online System (DROLS) becomes operational.
1979 —DDC officially changes its name to Defense Technical Information Center (DTIC).
1980 —DoD Information Analysis Center (IAC) Program is added to DTIC’s mission.
1994 —DTIC begins offering products and services via the Internet.
1995 —DTIC moves to its current location in the Andrew T. McNamara Headquarters Complex, Fort Belvoir, Virginia.
2004 —DTIC becomes a DoD Field Activity aligned under the Undersecretary of Defense for Acquisitions, Technology and Logistics reporting to the Director, Defense Research & Engineering (now Assistant Secretary of Defense for Research and Engineering (ASD(R&E)).
2008 —DTIC Online is launched, providing one Web site to search and access DoD research and engineering information.
2008 —DTIC launches DoDTechipedia , DoD’s scientific and technical information wiki. It is a wiki to facilitate increased communication and collaboration among DoD scientists, engineers, program managers, acquisition professionals and operational Warfighters. DoDTechipedia is a living knowledge base that reduces duplication of effort and encourages collaboration among program areas and connects capability providers with technology developers.
2009 —DTIC launches DefenseSolutions.gov, an idea portal for potential DoD Contractors to submit solutions to DoD challenges.
2010 —DTIC celebrates 65 years of meeting the scientific and technical information needs of the DoD community in support of the warfighter.

Embedded Librarians and Support to the Unified Combatant Commands (COCOMs)
DTIC Embedded Librarians provide onsite, direct support to COCOMs during major exercises. Reach-back support is provided by the DTIC Reference Team at DTIC Headquarters. Embedded Librarians:
- Follow daily battle rhythm of exercise
- Attend Commander’s Update Brief (CUB)
- Receive taskers or assignments
- Refer queries for reach-back support from DTIC staff
- Discuss research with assigned group
- Prepare quad charts, PowerPoint presentations and command briefings
- Conduct training for COCOM staff on DTIC resources
Embedded Librarians have participated in major exercises with United States Pacific Command (USPACOM) and United States Northern Command (USNORTHCOM) and have provided support to all 10 Unified Combatant Commands.
Information Analysis Centers
Information Analysis Centers (IACs) are research and analysis organizations chartered by the DoD and operated by DTIC (). IAC experts help researchers, engineers, scientists and program managers get the information they need, when they need it. DTIC manages 3 distinct IACs divided between Technical Area Tasks (TATs) and Basic Centers of Operations(BCOs), which enable quick access to S&T information worldwide. Basic searches (up to four hours of research) are free to DTIC registered customers. If your search requires more in-depth research, IACs can support you without your organization incurring common procurement cost.
