As an external user or alumnus, you can also use the TUM library. You’ll need a library card, which you can apply for at one of our branch libraries [4]. Your library number will be provided along with the card (11-digit number on the back of the card).

A New Password is Required for External Users an TUM Alumi!
With the migration to the new library system in January 2025, existing passwords (used with library numbers) are no longer valid. When logging into the OPAC for the first time after the migration, you must create a new password. Please use the "Forgot Password" function for this purpose.

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.
