How can I extend the loan period for borrowed media?

Log in to your account via the Account/Renewal tab in the catalog using your UB ID number and password. Your account balance shows all borrowed media. You can now extend the loan period of individual items or renew your entire account. Please note that you can only renew items ten working days before the loan period ends.

Items that have been reserved or renewed six times cannot be renewed. Subsequent renewals are also not possible.
