Shelfmarks can be found on the book (sticker on the spine) and in the Online Catalogue OPAC. Using the shelfmark you can find the books you have located in the Online Catalogue quickly and easily in the branch libraries.
Shelfmarks of the TUM University Library are structured as follows:
0003 MAT 005f 2009 L 23-1(12)+3
0003: The first four digits indicate the location. You can find out which location it refers to in each case by checking the "Holdings" tab in the OPAC under the individual entry.
MAT 005f: The letter/number combination is the so-called notation or classification number and stands for a specific subject area. Books on the same subject are therefore side by side and you can find what you need by browsing the shelves.
All classification numbers are detailed in the TUM Classification System.
2009: The number indicates the year of acquisition, not the year of publication of the book. On the shelves you will therefore find the new acquisitions at the end of a system location. Note that new editions are housed next to the older editions, regardless of when the later edition was acquired.
L: The letters A, B and C denote the size of the book; the letter L stands for books from the textbook collection.
23: is a sequential number.
-1: indicates the volume serial number of series or multi-volume publications.
(12): stands for the edition of the book (specified from the second editions onwards).
+3: The copy number for books where more than one is available under the same location mark.
