Call number
In libraries, every medium has a call number - this is the exact "location" of a book or journal. In the Katalog plus you can easily find out the call number.
The call number of a book
The call number shows exactly where the book is located in the library. It is structured according to a fixed system:
33QSL3746
- 33 = Location code: This indicates in which part of the building and on which level the book is located.
- QSL = system classification (also called notation): This tells which subject the book belongs to. For example, QSL stands for Nature Conservation and Environmental Law. The entire media stock of the University Library is arranged thematically, i.e. according to a classification system, so that books on the same topic are in the same place.
- 3746 = consecutive numbering: This is at the end of the call number and distinguishes individual titles with the same system classification.
Sometimes the consecutive number is followed by an edition number in brackets, a copy number with a plus sign or a volume count with a minus sign.
The call numbers of the schoolbook collection also provide information about the type of school and grade and the type of schoolbook materials.
The call number of a journal
The call number helps you to find a journal or newspaper in the library. A fixed scheme also applies here:
20-40J39
- 20 = Location code: This shows the part of the building and the level on which the journal is located.
- 40 = Subject code: All journals in a subject area are grouped under this code - in this case it stands for history.
- J = First letter of the journal: Articles such as the, a, an (also in other languages) are not counted as initial letters.
- 39 = consecutive numbering: This distinguishes individual journals within the same subject code.
