Classification Scheme

There are many standard systems of library classification in use, and many more have been proposed over the years. However, in general, classification systems can be divided into three types depending on how they are used:

1. Universal schemes

Covers all subjects, e.g. the Dewey Decimal Classification (DDC), Universal Decimal Classification (UDC), Library of Congress Classification (LCC), and Colon Classification (CC).

2. Specific classification schemes

Covers particular subjects or types of materials, e.g. Iconclass (art), British Catalogue of Music Classification, and Dickinson classification (music), or the NLM Classification (medicine).

3. National schemes

Specially created for certain countries, e.g. Swedish library classification system
