Library of Congress Classification (LCC)

LCC was originally developed by Herbert Putnam with the advice of Charles Ammi Cutter in 1897. It is a system which is very much used in research and university libraries in USA as well as in other countries. All bibliographical records from Library of Congress entail LCC as well as DDC numbers.


The most important features of the LCC are:




Broughton, V. (2004). Essential classification. London: Facet publishing. (Chapter 15 + 16 are about LCC).
