Knowledge Organization: Classification and Cataloguing Theory

Notes The most commonly used type of subject heading is a topical heading.
The most comprehensive tool for finding subject headings for any topic in a periodical
index or library catalogue is the official subject heading list for that index or catalogue.
One of the most extensive and commonly-used controlled vocabulary lists is the Library
of Congress Subject Headings (LCSH), which is used by most library catalogues.
Sometimes Library of Congress classification letters and numbers are listed after a subject
heading.

Since the LCSH is based on the Library of Congress collection, which is one of the largest
library collections in the world, many valid subject headings will only be found in the
largest or most specialized library catalogues and will not be included in most library
catalogues.

Subject headings gather in one alphabetical place in a catalogue all treatments of a subject
regardless of shelf location.

The library catalogue is vital function at the very centre of a library, and as such it is
always growing and changing to reflect the growing collection and to meet the changing
needs of the users.
