In bibliotek.dk there are some materials that can not be borrowed - or can only be borrowed by some:

• Materials on the Internet (e-books, audio books, online music, netfilm, eperiodicals etc.): Some of these materials are only available if your library has purchased access
• Restricted Rights: Some materials - especially movies - libraries have limited rights. They may for example only be lent to a municipality's own citizens. In these cases, you will get a warning, or request button is missing, and you will get a link to the libraries where you can borrow - if you are a registrated borrower
• Completely new material
