Free Information Tools for Chemists, Physicists, and Mathematicians

PubSCIENCE
http://pubsci.osti.gov/
Bibliographic database with abstracts (and some full text) from peer-reviewed journal articles in physics and chemistry. Provided by the DOE.
PrePRINT Network
http://www.osti.gov/ preprints/
Gateway to hundreds of preprint sites and servers, most of which are located on university web sites. The PrePRINT Network allows the user to search for full text math, chemistry, physics, biology, and environmental and materials science articles before they have been published. Provided by the DOE.
DOE Information Bridge
http://www.osti.gov/ bridge/
Full-text access to reports from the DOE from 1995 forward.
Energy Citations Database
http://www.osti.gov/ energycitations/
In addition to environmental science (see Table 4), this database covers mathematics, chemistry, physics, materials science, engineering, and computer science. Provided by the DOE.
arXiv
http://arxiv.org/
A preprint archive that resides at Cornell University and is funded by the U.S. National Science Foundation. ArXiv contains pre-publication full text of articles in the areas of physics, mathematics, and computer science.
NASA Technical Report Servers
http://techreports.larc. nasa.gov/cgi-bin/NTRS
Citations, abstracts, and in some cases full text of unclassified technical reports from NASA programs (Johnson, Golden, & Norrisey, 2000).
