AstroWeb: Astronomy/Astrophysics on the Internet Welcome to AstroWeb - a collection of pointers to astronomy-related information available on the Internet. The database is maintained by the AstroWeb Consortium , a collaboration involving 9 individuals at 7 institutions. In addition to classified lists of resource records, the Consortium also provides a utility to search the AstroWeb database: (WAIS search help) Most of the URLs in the database are tested three times a day to verify aliveness (see "AstroWeb Dead URLs" and "AstroWeb Unreliable URLs" ). The Consortium will be pleased to accept contributions of new resource records. You can use HTML forms to submit an addition or change to the Astroweb database review pending submissions review Astroweb records changed in the past month or send EMail to the Consortium This NRAO version of AstroWeb is recomputed at about 09:10 UTC each day, if the master database has been changed. Neither the individuals involved in the AstroWeb Consortium, nor their affiliated institutions, accept any responsibility for the contents or availability of information located at other Internet sites. 1/27/2003 2:57:25 PM The AstroWeb master database currently contains 3065 distinct resource records: Category Records Observing resources Telescopes Astronomical survey projects Telescope observing schedules Metereological information Data Resources Data and Archive Centers Astronomy Information Systems Publication-related Resources Abstracts of Astronomical Publications Full-texts of Astronomical Publications Astronomical Bibliographical Services Astronomy-related Libraries ...

The databases cover all the major journals, many minor journals, conference proceedings, several Observatory reports and newsletters, many NASA reports, and PhD theses. Users can query the database by author, astronomical object name (astronomy database only), words in the title, and words in the abstract text. The resulting list is ranked by how closely the paper matches the query. From this list, one can view the full record available for each of the selected publications.
