The 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
9.2 million records on Astronomy and Astrophysics, Physics, and arXiv e-prints.
The main body of data in the ADS consists of bibliographic
records. Full-text scans of much of the astronomical literature which can
be browsed or searched

Integrated in its databases, the ADS provides
