The SAO/NASA Astrophysics Data System Abstract Service provides a gateway to the online Astronomy and Physics literature. You can navigate this content using the following query interfaces:

  • Basic Search, which searches the entire body of literature (7,441,018 records) currently indexed in the ADS.

  • Astronomy and Astrophysics Search, an advanced interface which searches the 1,575,201 records currently in the Astronomy database, including 134,313 abstracts from Planetary Sciences and Solar Physics journals

  • Physics and Geophysics Search, an advanced interface which searches the 4,794,649 records currently in the Physics database, including 443,935 abstracts from APS journals and 273,856 abstracts from SPIE conference proceedings

  • arXiv Preprints Search, an advanced interface which searches the 514,647 records consisting of all the papers published in the arXiv e-print archive

  • Science Education Search, a basic interface to the literature in Science Education Research and related publications (a selected subset of publications from the above databases)

Each database contains abstracts from articles and monographs published in the different disciplines. The databases cover all the major journals, many minor journals, conference proceedings, several Observatory reports and newsletters, many NASA reports, and PhD theses.

The arXiv e-print database contains preprints submitted to the arXiv e-print archive. ADS maintains this database to allow searches on the latest literature being published, with links to the fulltext available from the arXiv.

We also provide access to scanned images of articles from most of the major and most smaller astronomical journals, as well as several conference proceedings series. All scanned articles are linked to the corresponding references in the ADS. They can be accessed through the search system linked to on this page or through ADS browse interface.

As an additional service to the astronomical community, ADS has also been maintaining a database of people involved in astronomy research. If you need to locate somebody in the community, you can use the astroperson search form.
