Set up all over the campuses, the 26 university libraries cover all subjects and domains. They provide access to over a million books, plenty of online resources, over 5,000 study seats, and numerous services. The National and university library of Strasbourg (Bibliothèque nationale et universitaire - BNU), 2nd biggest in France, is also open to students. Documents can be borrowed using the Campus Pass. Thanks to Eucor – The European Campus, the Strasbourg university community also has access to the libraries of 5 partner universities.
