In the search engine, if a book is available in the library, a book- or call number is displayed in each search result. This is a unique code (shelf mark) identifying every medium in our library collection. There are differences depending on the location. The printed books are systematically arranged. <Here> is an overview.
Location Building A 1. floor:
Fiction, children’s and young adult literature and biographies
The shelf mark designates the different areas. DR for the fiction literature, DJ for young adult books, B for biographies and J for books in the children’s area.
In each of these areas the books are organized by genre and arranged in alphabetical order by author.
Location Building B 1. floor:
Reference books and non-fiction literature:
In building B the shelves are arranged systematically from A-Z.
Example: Found book number: “QQ 000 C229”. The first two letters designate the academic discipline; in this case, “Q” means “Economics” (Wirtschafts-wissenschaften), “QQ” is the sub-category “Special business management textbooks”, the numerical sequence “000” is the additional sub-category – “General”. The following letter-number-sequence “C229” is the encoded author or editor name.
Useful information: The shelf mark shows the edition in brackets; the minus refers to the volume.
DVDs, audiobooks and games:
The shelf mark TT designates DVDs. They are grouped by genre and the film titles are arranged in alphabetical order. The shelves marked TT.J contain the children’s DVDs.
All audiobooks have the shelf mark TD, children’s audiobook TD.J. The audiobooks are grouped in alphabetical order by genre and author.
At present, the games aren’t arranged systematically.
