To be able to order books from the online catalogue, you have to log in first.
Click Search in the upper menu window and search for your desired book. In the result window, click on the link in the Items column. The now open window will show you whether the book is currently available or if not, the date when the book should be returned to the UL.
If you want to order this book, click Request and then OK! If you did not log in so far, you will be asked to do so at this point.
The book will then be waiting for you at the UL on the day of your order until the following workday. Do not forget to bring along your library card for pick-up.
