Abstract.
The Astrophysics Data System (ADS) provides access to
the
astronomical literature through the World Wide Web. It is a NASA funded
pro ject and access to all the ADS services is free to everybody
world-wide. It
can be accessed without login through any web browser.
The ADS Abstract Service allows the searching of three databases
with
abstracts in Astronomy (including Astrophysics, Planetary Sciences, and
Solar
Physics), Physics/Geosciences, and the arXiv E-prints from Cornell, with
a
total of over 5 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 astro- nomical literature back to volume 1. It contains the scanned pages of all the ma jor Astronomy journals (Astrophysical Journal, Astronomical Journal, As- tronomy & Astrophysics, Monthly Notices of the Royal Astronomical Society, and Solar Physics), as well as most smaller journals back to volume 1.
In order to improve access from different parts of the world, we have set up 12 mirror sites of the ADS in different countries in Europe, Asia, Australia and the Americas. The ADS is available at: http://ads.harvard.edu
