Porta Hebraicorum is a pilot scheme for the cooperative work of scientific teams specializing on the history and culture of the Jews, computer science and librarianship. The term Hebraica refers to written documents in Hebrew letters.
New methods and techniques of computer science are applied to research, structure, catalogue, archive, and present historic and bibliographic information about such documents.
Object of research are some of the worldwide most significant Hebraica preserved in the Bavarian State Library. They survived the Second World War and National Socialism nearly undamaged. They count about 2700 titles from the years 1501 - 1933. Similar libraries have been transferred to other countries or destroyed.
