Information about the classification systems used in the NTNU University Library. The library uses different classification systems because our collections consist of books and documents from three different libraries.

UDC #

All the libraries at Gløshaugen use UDC (Universal Decimal Classification). UDC is designed for subjects and topics in technology.

UDC is divided into 10 main classes:

0: Science and Knowledge, Organization, Computer Science, Information Science, Documentation, Librarianship, Institutions, Publications

1: Philosophy, Psychology, Ethics

2: Religion, Theology

3: Social Sciences

4: vacant

5: Mathematics, Natural Sciences

6: Medicine, Technology; includes Civil Engineering and Design

7: The Arts, Architecture, Sport; includes Architecture and Design

8: Linguistics, Literature

9: Geography, Biography, History

Each main class can be further divided into ten sub-classes, which can be further divided into ten sub-classes, which can be further divided into ten sub-classes. This system can result in long numbers; to make the longer numbers easier to read, an auxiliary sign is inserted after every third digit. In the UDC system we use different auxiliary signs to describe complex subjects; the auxiliary signs need to appear in a certain order.

UDC - industrial design #

The library uses industrial design as label for subjects within design and product design. More than one UDC class will be relevant for those who study or do research in this field, depending on the main focus of study. Literature bought for industrial design, or where industrial design is an essential part of the content, will be tagged with a design number in addition to the main subject number.

Music classification #

To organise notes, the Music Library uses a foreign classification system that was first used to organise the music collection in the Deichman Library. Now it’s also used by the Norwegian Academy of Music and the music conservatory libraries. The system has local varieties. The classification is built up by sorting instruments and groups of instruments. This means that e.g. all violin notes are organised and stored together. Scores do not follow the same classification. Grand scores, student scores and piano scores are treated as separate classes.

Examples:

One sonata (one composer) for the flute and the piano is labelled: H 1111.

A collection of musical pieces (several composers) only for the flute is labelled: H 1102.


A collection of duets for two violins (one composer) is labelled: F 100

Two viola: F 101

Two celli: F 102


Song books are labelled R 6, while children’s song books are labelled R 61


Main classes #

C - Keyboard instrument

D - Organ and harmonium

E - Stringed instruments

F - Chamber music for stringed instruments

G - Chamber music with piano or basso continuo
