Our books are clearly arranged by topic according to the MSC - Mathematics Subject Classification, which also describes the content of each book. So every book has a MSC call number (shelfmark) and possibly several other MSC subject codes to describe its content. MSC codes can easily be searched in the Knowledge Portal Primo search box.

Mathematics Subject Classification is also used by the American Mathematical Society and the Zentralblatt Math for indexing books and articles.

The MSC is a hierarchical scheme, with three levels of structure:

General groups and materials have a two level structure and are represented with a hyphen:

Our call number is made up of the MSC subject code and the first two letters of the first author or editor:

Our books are sorted first by MSC, then within the subject code alphabetically by author, then ascending editions of the same book and at last sorted by copy count. The call number can be found at the bottom of the spine of every book.
