Person-related institute cards

Person-related institute cards are transferable, that means that, in addition to the person named in the card and responsible, other people (e.g. Hiwis) may use the card. Lecturers or employees of the University can receive an institute card.

The person-related institute card is not managed through the University SIAM user account (ac-account) of the lecturer or employee, instead access to this library account happens via a separate ub-account that is activated for library services exclusively. This ub-account has the same rights and responsibilities as those connected to a personal ac-account.

You can apply for a person-related institute card at both circulation desks (City and Vaihingen branch) on workdays (except Saturday) between 8 a.m. and 4 p.m. The required registration form with the regulations involved is found here.
