NASA ASTROPHYSICS DATA SYSTEM

Project Description
The Astrophysics Data System (ADS) is a NASA-funded project whose main
resource is an Abstract Service, which includes three sets of
abstracts: 1) astronomy and astrophysics, containing approximately
255,000 abstracts; 2) instrumentation, containing approximately
460,000 abstracts; and 3) physics and geophysics, containing
approximately 220,000 abstracts. Each dataset can be searched by
author, object name (astronomy only), title, or abstract text words.
In addition, they have extended the abstract service to include links
to scanned images of over 40,000 journal articles for articles
appearing in most of the major astronomical journals. In addition to
the Abstract Service, the ADS provides access or pointers to
astronomical data catalogs and data archives, thereby making data
collected by NASA space missions available to astronomers. In most
cases coverage begins in 1975 but older materials are in the process
of being added. The database includes journal articles, NASA and
other reports, conference proceedings, and some Ph.D dissertations.
