"2.4  Citations and References:

The use of citation histories is a well known and effective tool for
academic research ([Garfield 1979]).  In 1996 the American Astronomical
Society purchased a subset of the Science Citation Index from the Institute
for Scientific Information, to be used in the ADS; this was updated in 1998.
 This subset only contains references which were already in the ADS, thus it
is seriously incomplete in referring to articles in the non-astronomical
literature.  This citation information from ISI spans January 1982-September
1998.

The electronic journals all have machine readable, web accessible, reference
pages.  The ADS points to these with a hyperlink where possible.  Several
publishers allow us to use these to maintain citation histories; we do this
using our reference resolver software.  The same software is also used  by
some publishers to check the validity of their references, pre-publication.

Additionally we use optical character recognition to create reference and
citation lists for the historical literature, after it is scanned
([Demleitner, et al. 1999]).  This process has handled over 10 million
references and added over 6 million parsed references to the ADS citation
database."

Abstract:   The Astrophysics Data System (ADS) provides access to the
astronomical literature through the  World Wide Web. It is a NASA funded
project and access to all the ADS services is free to everybody world-wide.
The ADS Abstract Service allows the searching of four databases with
abstracts in Astronomy, Instrumentation, Physics/Geophysics, and the LANL
Preprints with a total of over 2.2 million references. The system also
provides access to reference and citation information, links to on-line
data, electronic journal articles, and other on-line information. The ADS
Article Service contains the full articles for most of the astronomical
literature back to volume 1. It contains the scanned pages of all the major
journals (Astrophysical Journal, Astronomical Journal, Astronomy &
Astrophysics, Monthly Notices of the Royal Astronomical Society, and Solar
Physics), as well as most smaller journals back to volume 1. The ADS can be
accessed through any web browser without signup or login. Alternatively an
email interface is available that allows our users to execute queries via
email and to retrieve scanned articles via email. This might be interesting
for users on slow or unreliable links, since the email system will retry
sending information automatically until the transfer is complete. There are
now 9 mirror sites of the ADS available in different parts of the world to
improve access. The ADS is available at: http://ads.harvard.edu.
