Most of our old books and periodicals, but also literure written in not commonly known languages, as well as very specialized literature are shelved in closed stacks.
When searching the catalogue and clicking on "Verfügbarkeit prüfen", such titles will have "Magazin" as the location.
Some of the titles in the closed stacks have a lending restriction. They can be ordered for use in one of the reading rooms.
After ordering, the lending system tells you when the item will be ready for collection. It usually takes half a day until it can be collected from the "Selbstabholregal" behind the issue desk.
