The NTRS collects scientific and technical information from NASA's technical report servers and non-NASA sites. The full text of selected NASA documents are freely available. Many NASA documents may be ordered from CASI (The NASA Center for Aerospace Information.)

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 7.8 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through highly customizable query forms, and full-text scans of much of the astronomical literature which can be browsed or searched via our full-text search interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 8.3 million records maintained by our collaborators.

This database is built around a master list of extragalactic objects for which cross-identifications of names have been established, accurate positions and redshifts entered to the extent possible, and some basic data collected. Bibliographic references relevant to individual objects have been compiled, and abstracts of extragalactic interest are kept on line. Detailed and referenced photometry, position, and redshift data, have been taken from large compilations and from the literature. NED also includes images from 2MASS, from the literature, and from the Digitized Sky Survey. NED's data and references are being continually updated, with revised versions being put on-line every 2-3 months.

The SIMBAD astronomical database provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system. SIMBAD can be queried by object name, coordinates and various criteria. Lists of objects and scripts can be submitted. Links to some other on-line services are also provided.

An index to the scientific technical and medical literature covering 14,000 scholarly titles including 2,700 titles in Social Science, Psychology, and Economics. Updated daily.

Academic OneFile has over 8,000 peer-reviewed journals, the majority in full-text, from the world's leading journals and reference sources. Extensive coverage of the physical sciences, technology, medicine, social sciences, the arts, theology, literature and other subjects. Full text articles are available in both PDF and HTML. Includes full-text coverage of the New York Times back to 1995. Updated daily.

A database of over 1,700 journal titles, covering the life, physical, technical and social sciences. Titles start with the initial volume of publication; all titles have tables of contents and abstracts, and most have full text articles. Green boxes indicate subscribed titles, white boxes are for unsubscribed titles, yellow boxes are complementary, and white with red boxes are partner web sites. Articles from unsubscribed titles must be obtained from Tufts Document Delivery Services.
