The database contains personal data relating to Jews who were present in Krakow during the Second World War. It includes information on places of residence, hiding places, traumatic experiences, and places of residence after 1945. The database is continuously updated and expanded with biographical profiles of individual persons, depending on the availability of historical and archival sources. Our team currently holds data on nearly 5,000 individuals, which is being systematically processed and incorporated into the database by members of the research team and interns.
