URLs of Note

URLs (Uniform Resource Locators) provide the address information needed to make a link with a World-Wide Web site. A popular user interface to the WWW is NCSA Mosaic. A number of lists of astronomical resources have been established, and coordination between those maintaining these lists has been undertaken by a group calling itself the ``AstroWeb Consortium''. Current members are: Jackson (STScI), Wells (NRAO), Koekemoer (Mount Stromlo), Egret and Heck (Strasbourg Observatory), and Adorf and Murtagh (ST-ECF). The AstroWeb Consortium has formed a common resource listing, and assembled various tools - in particular, automated submission procedures for new URLs, and automated checking procedures to verify that URLs still respond to accesses as expected. Currently, more than around 1000 astronomically-relevant URLs are available. At URL http://fits.cv.nrao.edu/www/astronomy.html, these astronomical resources are categorized under: Observing Resources, Data Resources, Organizations, Software Resources, Publication-Related Resources, People-Related Resources, Various Lists of Astronomy Resources, Astronomical Imagery, and Miscellaneous Resources.

A short list of URLs for sites which support user services - archive research, or observing - is given below. No guarantee can be made that required information will be found at these sites. However, the momentum behind the World-Wide Web is currently very great, and the information available through Mosaic (or other browsers) is growing constantly in quality and quantity. The World-Wide Web is thoroughly compatible with other network-based access mechanisms: WAIS, Gopher, FTP, telnet, etc., and in fact provides a common user interface to all of these.
