The National Technical Information Service (NTIS) is an agency within the United States Department of Commerce. The primary mission of NTIS is to collect and organize scientific, technical, engineering, and business information generated by U.S. Government-sponsored research and development, for private industry, government, academia, and the public. The systems, equipment, financial structure, and specialized staff skills that NTIS maintains to undertake its primary mission allow it to provide assistance to other agencies requiring such specialized resources.
Under the provisions of the National Technical Information Act of 1988 (15 U.S.C. 3704b), NTIS is authorized to establish and maintain a permanent repository of non-classified scientific, technical, and engineering information; cooperate and coordinate its operations with other Government scientific, technical, and engineering information programs; and implement new methods or media for the dissemination of scientific, technical, and engineering information, including producing and disseminating information products in electronic format and to enter into arrangements necessary for the conduct of its business.
NTIS serves the United States as a central repository for government-funded scientific, technical, engineering, and business related information to assure businesses, libraries, academia, and the public timely access to approximately 2.5 million publications covering over 350 subject areas. The stated aim of NTIS is to support the Department of Commerce mission to promote the nations economic growth by providing access to information that stimulates innovation and discovery.
