Books are arranged according to a thematic classification system in over 40 rooms of the library.
The call number, which helps you to find specific books on the shelves, consists of a combination of letters and numbers, for example, ERZ XD1 1408-1(2)A.
The call number can be deciphered as follows:
- The first class mark ERZ = inventory of the Institute of Educational Science
- The second class mark, (in this case, XD1) = "Theorie und Geschichte der Pädagogik als Wissenschaft" in Room 031
- The number 1408 = catalogue number
- Supplementary information: volume serial number for multi-part publications, e.g. …-1, for the edition, e.g. … (2), and for copies of a book, e.g. A (1st copy), B (2nd copy) or C (3rd copy) etc.
