Re-classification of Library Materials

books image
The Multi-year project to re-classify the Library's entire 500,000 plus items to the Library of Congress Classification scheme which began in 2006 was completed at the end of 2010. Library users will now be able to fully enjoy the benefits of an integrated library collection whereby materials are shelved by subjects regardless of language.

The following tables show the call number locations in the General and Large Book (LBK) Collections:

Formerly, the Library employed two different classification schemes, Dewey Decimal Classification (DDC) and the New Classification Scheme for Chinese Libraries (commonly known as Lai's classification) for its English and Chinese materials. As the collections were maintained in separate locations, users had to handle two different types of call numbers and had to go to separate locations to find materials on the same topics. By converting to the Library of Congress Classification scheme, the Library will be able to offer better subject access to its English and Chinese materials. In addition, the Library of Congress Classification is also the preferred classification system for many academic libraries, including most of those in Hong Kong. When visiting other academic libraries in Hong Kong, users will find the call number system familiar. For a subject mapping table between, LC, DDC and Lai's, please see
