Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the new ADS <a href="https://ui.adsabs.harvard.edu/">modern search form</a> as well as a <a href="https://ui.adsabs.harvard.edu/#classic-form">classic search form</a>. A <a href="https://ui.adsabs.harvard.edu/#paper-form">browsable paper form</a> is also available.</p> <p>In addition to maintaining its bibliographic corpus, ADS tracks citations and usage of its records to provide advanced discovery and evaluation capabilities. Integrated in its collections, ADS provides access and pointers to a wealth of external resources, including electronic articles available from publishers’ websites, astronomical object information, data catalogs and data sets hosted by external archives. We currently have links to over 13.3 million records maintained by our collaborators.
