Assigning Subject Headings and Subject Subdivisions for Cataloguers

Abstract

The Subject headings is a vital part of bibliographical because they allow users to find needed information resources, in addition to searching by title, author, or other data. Subject headings might be words, groups of words, or phrases. The Library of Congress divides subject headings into three categories: main heading, subheadings, and independent subheadings with diverse criteria and usage patterns. Headings and subheadings may be essentially defined as channels for user access to precise information resources required. Librarians must keep up with news to be aware of new vocabulary usage, including regularly updating criteria for the operational manual facilitating word choice and appropriate subject definitions.
