There is no library card for RUB libraries; you can borrow books via the RUB Bib app, for which you need an account:
Employees automatically receive a library account via their LoginID
Enrolled students automatically receive a library account via their LoginID
Other researchers who are registered with the city they reside in can apply for access to the University Library themselves. If a LoginID is requested for them by their host chair, we recommend waiting for it so that their account can be linked to it.
Other researchers who are not registered with the city they reside in can apply for access through the Welcome Center: welcome-centre@rub.de.
If you have any questions, please always feel free to reach out to us.
