Astrophysics Data System (ADS)

The large volume of research in astronomy and related fields published every year makes it difficult to keep up. The Astrophysics Data System (ADS) is a digital portal containing bibliographic information on more than 13 million publications in astronomy, astrophysics, and physics. In addition to full abstracts and links to published works, ADS maintains a list of citations for the publications, with full text searches available for many. The databases also catalog experimental and observational datasets,with links to research data and software hosted by other scholarly archives. ADS is operated by the Center for Astrophysics | Harvard & Smithsonian under a grant from NASA.
