Bibliographic Catalog of Variable Stars

The Bibliographic Catalog of Variable Stars (BCVS) is a database of bibliographic entries regarding variable stars, stored at the Centre de données astronomiques de Strasbourg (CDS). Information was assembled through the 20th century as a library card catalog, and was added to the CDS in the 1970s, with some updates into the 1990s. An analogous Bibliographic Catalog of Suspected Variable Stars (BCSVS) was also assembled, entries moved to the BCVS when appropriate.
