SAO / NASA天体物理学数据系统（ADS）是供天文学和物理学研究人员使用的数字图书馆门户网站，由Smithsonian天体物理观测站（SAO）在NASA的资助下运营。
ADS维护着三个书目数据库，其中包含1300万条记录，涉及天文学和天体物理学，物理学和arXiv电子版出版物。主要的天文学和物理学出版物的摘要和全文可通过新的ADS现代搜索表以及经典搜索表进行索引和搜索。还提供可浏览的纸质表格。
除了维护其书目语料库之外，ADS还跟踪其记录的引用和使用情况，以提供高级的发现和评估功能。 ADS集成在其数据库中，可访问和指向大量外部资源，包括可从出版商网站上获得的电子文章，天文物体信息，数据目录和外部档案馆托管的数据集。目前，我们可以链接到合作者保存的1,330万条记录。如此深入的信息使文献计量学和信息科学等领域的许多出版物（被引用，未被引用）成为可能。
The SAO/NASA Astrophysics Data System (ADS) is a digital library portal for researchers in astronomy and physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant.
The ADS maintains three bibliographic databases containing more than 13 million records covering publications in Astronomy and Astrophysics, Physics, and the arXiv e-prints. Abstracts and full-text of major astronomy and physics publications are indexed and searchable through the new ADS modern search form as well as a classic search form. A browsable paper form is also available.
In addition to maintaining its bibliographic corpus, the ADS tracks citations and usage of its records to provide advanced discovery and evaluation capabilities. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles available from publisher’s 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. This depth of information has enabled a number of publications (refeered, non-refereed) in fields such as bibliometrics and information science.
Please note that all abstracts and articles in the ADS are copyrighted by the publisher, and their use is free for personal use only. For more information, please read our page detailing the Terms and Conditions regulating the use of our resources.
The importance of ADS’s role in supporting the scientific community has been recognized by societies and individuals.
