Editing Astrophysics Data System (section)

==Coverage==
The database now contains over fifteen million articles. In the cases of the major journals of astronomy (''[[Astrophysical Journal]]'', ''[[Astronomical Journal]]'', ''[[Astronomy and Astrophysics]]'', ''[[Publications of the Astronomical Society of the Pacific]]'' and the ''[[Monthly Notices of the Royal Astronomical Society]]''), coverage is complete, with all issues indexed from number 1 to the present. These journals account for about two-thirds of the papers in the database, with the rest consisting of papers published in over 100 other journals from around the world, as well as in conference proceedings.<ref name="data" />

While the database contains the complete contents of all the major journals and many minor ones as well, its coverage of references and citations is much less complete. References in and citations of articles in the major journals are fairly complete, but references such as "private communication", "in press" or "in preparation" cannot be matched, and author errors in reference listings also introduce potential errors. Astronomical papers may cite and be cited by articles in journals which fall outside the scope of ADS, such as [[chemistry]], [[mathematics]] or [[biology]] journals.<ref>{{cite web |url=http://adsabs.harvard.edu/abs_doc/journals1.html |title=ADS Bibliographic Codes: Journal Abbreviations |publisher=Harvard-Smithsonian Center for Astrophysics |access-date=30 October 2008 |archiveurl=https://web.archive.org/web/20080430032916/http://adsabs.harvard.edu/abs_doc/journals1.html |archive-date=30 April 2008}}</ref>
