The database comprises two card catalogues – topographic and genealogical – created by the Czech historian August Sedláček (1843–1926). Both card catalogues, which together contain over 400,000, are kept at the Institute of History of the CAS. The database contains historical data on individual aristocratic families and locations in Bohemia and Moravia, based on the study of archival and library resources, mainly in Czech and Moravian archives. The notes within entries are primarily arranged in chronological order. The individual cards contain information of varying quality and quantity. The information was transcribed and itemized in the database so as to permit searching by simple words, names, places, dates and types of events covered by the records. In addition to a structured record of card content, the database always contains also a digital (scanned) image of each card.
