NASA Astrophysics Data System

The Astrophysics Data System (ADS) is a digital library for Physics, Astrophysics and Instrumentation. It is a NASA-funded project which maintains three bibliographic databases containing more than 4.5 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 the Abstract Service query forms, and full-text scans of much of the astronomical literature which can be browsed though the Browse interface. The abstracts database contains data from several sources, including NASA's Scientific and Technical Information group (STI), journal publishers SIMBAD, NED, and OCR'd from table of contents.

Please note that all abstracts and articles in the ADS are copyrighted by the publisher, and their use is free for personal use only. Read the Terms and Conditions regulating the use of the resources.
