Loans, returns and loans account

All books of the library are in open access and can be taken directly from the shelves. To check out items you can use the self-service checkout or go to the loans desk with your items. Please note: To check out books for the whole semester (see 'textbook collection') or to pick up books you ordered or reserved, please go to the loans desk (see 'opening hours').

Items can be returned at the loans desk or at the self-service check-in (located outside the library). Please note: Items you ordered from the Central Library or via interlibrary loan must be returned at the loans desk!
