As soon as you have registered, you can log in to the website with your social security number and pin code. When logged in you can reserve media in the catalog. When you have collected the library card, you get access to more services such as borrowing books and e-media, interlibrary loans, booking a computer and using databases.
If you have a library card, but have lost it, you do not need to fill in this form. It is enough that you visit the library and show identification.
