The Virtual Observatory (VO) project will provide a global network platform to support modern astronomical research with fast and easy access to distributed archives via a unified interface and data model. Our aim is to include the historical photographic plates of the Potsdam observatory into this database in the framework of GAVO, the German contribution to VO. This work is part of the DFG project 436 BUL. The Postdam collection of wide-field plates consists of 11 archives, obtained from 1879 to 1970 (see Catalogue of Wide-Field Plate Archives, version 5.0, March 2005, http://www.skyarchive.org/catalogue.html), with a total amount of about 10000 plates and films stored not only in Potsdam but also in Leiden and Sonneberg. Apart from the long timeline provided for the observed objects, the archives reflect the history and development of the Potsdam observatory and of astronomical photography as well. The first astronomical photographs represent a scientific treasure. They offer the possibility to follow the photometric behavior of astronomical objects for about 120 years. This information is unique, because no more reproducible. Our aim is to digitize the old plates as long as their physical status does still allow it, and continue their systematic incorporation into the already existing Wide-Field Plate Database. These data can be used to search for any kind of long-term brightness variations like new flare stars or rapidly varying stars (Froehlich et al., 2002, A&A 391).
