Abstract: WEBDA ( is a site devoted to stellar observational data, such as chemically peculiar stars, in stellar clusters in the Milky Way and the Small Magellanic Cloud. It is intended to provide a reliable synthesis of the available data and knowledge about these objects. The success of WEBDA is documented by its worldwide usage and the related acknowledgements in the literature: more than 450 refereed publications within the last seven years acknowledge its use. It collects all published data for stars in open clusters that may be useful either to determine membership, or to study the stellar content and properties of the clusters. The database content includes measurements in most photometric systems in which cluster stars have been observed, spectroscopic observations, astrometric data, miscellaneous other useful information, as well as an extensive bibliography. Several powerful tools help to plot, query and extract the data, which can be directly retrieved via http. At the time of writing, about four million individual measurements are included in the database. The Star Clusters Young & Old Newsletter (SCYON), a bi-monthly newsletter devoted to star cluster research with about 600 subscribers, is hosted in parallel with the database.
