Loan and Renewal
The loan period for books and doctoral dissertations is one month. During this time, the item is on loan to you without any restrictions. Shortly before the due date, the Library will send you a courtesy e-mail reminder. Most library items are renewable (see below). The Library reserves the right, under justified circumstances, to recall renewed materials prior to the due date.
Once you have found the desired item ( a book, journal, or audio-visual resource) in the Online Catalog, click on the "Request/Hold" or, if relevant, the "Copy of the Article" button. You may place items on hold if the following situations apply:
- An item is checked out or on reserve for another patron. Check the availability status by consulting the Online Catalog. Placing a request puts you on a waiting list for that item.The newly acquired item has the catalogue status "In Process" (received but not yet ready for circulation) or is on display in the new acquisitions shelf. Please note that reference copies cannot be placed on hold.
- The item is shelved elsewhere (in the departmental library Helmholtzstraße, closed stacks, or a University institute) and you wish to pick it up in the central library. Patrons of the departmental library Helmholtzstraße can also place items on hold for pick up in the departmental library.
You may also request scanned (or paper) copies from collection items.
Renew materials online by either self-renewal via the online catalogue or filling out the Renewal Request Form. Normally, a renewal is granted unless the book has a hold, you have reached the maximum amount of renewals allowed online (6), or unpaid fines or fees are on your account.
