Retrieving e-media

For licensing reasons, numerous electronic resources (e-books, journals, databases) can only be used by UDE members within the university network.

External users can access these e-media at the PC workstations in the GW/GSW and LK libraries. Access to electronic media from home, e.g. via VPN, is not possible.

Tips & tricks

Primo, the catalogue of the UL
In Primo, you search the local library catalogue and other electronic sources in an integrative user interface.

Campus delivery service
All lendable and available media can be ordered from the branch libraries on the other campus via campus delivery service at no charge.

Interlibrary loan
Literature which is not available at the Duisburg-Essen UL can be ordered via interlibrary loan. For each order, a fee of 1.50 € is due.

Databases and various electronic resources are available only to UDE members due to license agreement reasons and are available at some PC workstations in the Humanities and Social Sciences Library without limitation.
