The VizieR Catalogue Service is an astronomical catalog service provided by Centre de données astronomiques de Strasbourg (CDS, Strasbourg Data Centre for astronomy). The origin of the service dates back to 1993, when it was founded by the European Space Agency as the European Space Information System (ESIS) Catalogue Browser. Initially intended to serve the space science community, the ESIS project pre-dates the World Wide Web as a network database allowing uniform to a heterogeneous set of catalogues and data.
