Media reclaims suspended
Please ignore due dates and status notifications in your library account, as these are currently not applicable. Loan periods and media reclaims are suspended until further notice. You will not incur any costs, even if loan periods expire.

What can I find in OPAC?
In the OPAC you will find all books and journals available at the TUM University Library – both printed and electronic. You can order and reserve books, check the borrowing status of items and keep tabs on your loans in your library account.
Individual articles from journals, newspapers or conference proceedings are not listed. OPACplus and databases are available for this purpose.
What can I find in OPACplus?
In OPACplus you will find scientific materials of all kinds, especially articles from journals, newspapers, conference proceedings and much more.
A central index lists the University Library's media collections as comprehensively as possible, including both printed and electronic media. Depending on agreements with publishers and providers, bibliographic metadata, abstracts and electronic full texts are available.
OPACplus is particularly suitable for searching for media that are available as electronic full texts at the University Library.
How do I find information on my topic?
The OPACplus is a good starting point for the thematic search. It is our interdisciplinary research tool for scientific materials of all kinds.
However, for in-depth thematic research we recommend our specialist databases, in which you will find scientific papers, statistics, company data, facts, articles from journals, newspapers, conference proceedings and much more.

Why do I have to select a a check-out library?
This is the only way we know in which branch library we should deliver your requested items. You have to indicate the check-out library of your choice before your search, so that transport times, order options and the status of items are displayed correctly in the OPAC.
Does the selection of the check-out libray limit my search?
Irrespective of the branch library you have chosen as your check-out location, your search will automatically cover the entire TUM Library collection.
Why do I also have to select a check-out library for my library account?
Strictly speaking, this is not really necessary. However, if you start a search directly after looking into your account and order items, they would all be delivered to the default branch. In order to spare you such unnecessary misorders, we always ask for the potential pick-up location. Just to be on the safe side.

Why does it make sense to log in before the search?
