Why should I log in before starting a search?
When you are logged in, you have full access to all ordering functions.
Why do I sometimes need to log in a second time for e-media access?
Whenever you log in to the OPAC or e-media, you use TUM's web login service (Shibboleth Single Sign-On). By selecting the "stay signed in" option, you usually won't need to enter your TUM ID a second time, as long as your browser remains open.
However, depending on the login sequence, transmitted data, or the publisher's requirements, you may still be prompted to enter your TUM ID again.
External library users and TUM alumni can access our e-media collection on reading room PCs at our branch libraries.
