The national library database
In Denmark borrowing books etc. is free of charge.
Furthermore, you may request books, movies, music etc. from all of Denmark's libraries (ie. public libraries, university libraries, educational libraries) by requsting via the site bibliotek.dk.
The Business Academy's library is receiving requested books from other libraries twice a week.
Due to the complicated rights to electronic information, it is not possible to access other libraries' collection of ie. e-books or databases, unless you're a patron of the library in question.
