How to search e-books
How to use e-books
University members of the UDE can use licensed e-books regardless of time and location. For access from outside the campsite, please log in via Shibboleth or VPN. For both login methods, your UDE identification (= Unikennung) and the corresponding password are required.
External users can use the PC workstations in the branch libraries for their research. It is possible to store excerpts from e-books on a USB flash drive or print them out for a fee.
Through access via VPN (Virtual Private Network) you build a tunnel to the UDE network. All your data traffic is transmitted via an encrypted connection via the UDE VPN server. As long as the connection exists, your computer is assigned an IP address from the university network.
Usually, e-books can be used by several users simultaneously.
For some e-books only a limited number of simultaneous accesses is available. In this case, you will be notified when all available licenses are used. Please try again after some time.
