The catalogue describes foreign-language books, periodicals, dissertations and offprints, as well as publications in Oriental languages. To find a publication, open a letter or combination of letters, where you find entries with the same beginning (e.g. ble > Blebelius, Thomas). Publications in Oriental languages (e.g. Hebrew, and others) can be found under the division Z_Hebraic. The division Z_y contains materials that were at the time of digitisation undergoing the availability check. The catalogue is organised in alphabetical order, following the Prussian rules.
