Structure of the Deutsche Nationalbibliografie and the new publications service

Since the bibliographic year 2004, the Deutsche Nationalbibliothek (German National Library) has structured the different series of the Deutsche Nationalbibliografie and the New Release Service in accordance with the Dewey Decimal Classification (DDC).

The structure of the Series A, B and H is based for the most part on the two uppermost hierarchical levels of the DDC (the 100 Division or Second Summary). Discrepancies were allowed by integrating the third level (the Thousand Sections or Third Summary) of DDC and the fourth level twice whenever it was necessary to preserve formerly-used subject groups such as Military Science (Class 355) or Comics, cartoons, caricatures (Class 741.5). In two disciplines several DDC Classes of the Second Summary were combined to preserve the context of well-known disciplines such as Philosophy (Class 100, comprises DDC Classes 100, 110, 120, 140, 160, 170, 180 and 190) and Theology, Christianity (Class 230, comprises DDC Classes 230 - 280).

School textbooks and juvenile literature are exempted from the DDC structure, as they would be separated and scattered over many different classes. Fiction and poetry can be searched in its own category or in DDC subject classes 800 - 891.8 where it is identified by the additional classification of subject class B.

Series M (Printed Music and Music Publications) and T (Recorded Music) of the Deutsche Nationalbibliografie are also organised acording to DDC. Deeper hierarchical levels of DDC of up to six digits are used here in order to preserve retrieval possibilities similar to the previous structure.

Series C (Maps) represents one part of DDC Class 910 (Geography and travel).
