Description VizieR provides access to the most complete library of published astronomical catalogues and data tables available on line, organized in a self-documented database. Query tools allow the user to select relevant data tables and to extract and format records matching given criteria. Specific care has been taken for optimizing access to some very large catalogues such as Guide Star Catalogs, the USNO-A2, or the 2MASS last release.

VizieR is a joint effort of CDS(Centre de Données astronomiques de Strasbourg) and ESA-ESRIN (Information Systems Division). VizieR has been available since 1996. Note that VizieR does not contain all available online catalogues; some catalogues are not suitable and some less frequently used catalogues have not yet been incorporated into the VizieR database. These last ones can be accessed by FTP from the Astronomer's Bazaar.
