The Ornithological Institute’s library is an open-access library with a stock of around 20 000 items. Most items are freely accessible and are marked “Lesesaal” (Reading Room) in the catalogue.
Some older books, especially older editions, are stored in a mobile shelving system where they are also freely accessible to users. These books are marked “Magazin” (Archives) in the catalogue.
Particularly old and valuable items are kept in storage and are marked “Sondersammlung” (Special Collection) in the catalogue. They can only be viewed on request.
About 500 items are added to the library every year. Besides purchases, new additions also come from donations, legacies and review copies.
