How complete are the citations/references in the Abstract Service?
In early 1997 we started compiling for a subset of the bibliographic entries in the astronomy database their list of references and citations (the references of a paper are the papers cited by it; the citations of a paper are the papers which cite it). The original dataset used to create these cross-references was purchased from the Institute for Scientific Information (ISI), producer of the Science Citation Index, and consists of references from articles published by the major astronomical journals between 1980 and 1998 to articles in the same date range. (Please note that since the cross-references used to create the lists of citations and references in this dataset are self-contained, we cannot guarantee their completeness.) In 1999 we started extracting reference lists from the full-text of papers available in the ADS article service or provided to us by the journal publishers. As of October 2001, we have parsed and identified over 6 million references from the body of full-text ar

In October 2007 we gained access to CrossRef’s metadata, which includes references from many articles in the physical sciences. As of January 2008 we have parsed and identified over 30 million references from all the sources of bibliographic metadata available to us. While the ad
