Libraries using the Library of Congress (LC) subject headings can increase the effectiveness of their subject access. This can be accomplished through one of four methods for applying an increased number of headings: the addition of subject headings in situations where none have been supplied by LC; the use of pattern secondary headings; the use of major + minor techniques; and the use of minor + major techniques. Each of these methods will provide additional subject access to supplement that produced by the Library of Congress.
