In addition to the Classification, the subject index makes the printed books of the library accessible by referencing individual thematic search terms (subject terms) to the corresponding subject group. The links in the left and middle column take you directly to the appropriate hits in the online catalogue, the links in the right column refer to the subject group index (SGV).
Note: E-books and journals are not sorted by subject groups. The textbook collection is sorted by its own subject abbreviations, which are also used to find e-books. Media of the textbook collection can usually still be found via this directory, since usually 1 copy is available as monograph.
