The most comprehensive physics and astronomy article database. SAO/NASA Astrophysics Data System (ADS) includes three bibliographic databases: Astronomy and Astrophysics, Physics and Geophysics, and arXiv e-prints. ADS also links out to data catalogs and archives.
Database of electronic preprints covering physics, astronomy, math, computer science, quantitative biology, and statistics. (Preprints are drafts of articles; many will later go through a formal peer-review process and be published in scholarly journals.) ArXiv is also available in the database ADS (Astrophysical Data System).
