To what extent may the university library provide copies from books and journals via Interlibrary Loan to its users?

According to §60e German Copyright Law, the university library may provide paper copies consisting out of up to 10% of a medium.
Articles from professional or scientific journals may be provided as a whole.
On the other hand, the delivery of individual articles from newspapers or general-interest or newsstand magazines (for example Der Spiegel or Focus) is not permitted.
