LCSH History 1898 marked the advent of the new Library of Congress
dictionary catalog with the integration of alphabetically arranged author, title and subject entries now known as LCSH.
First published in 1909 as the Subject Headings Used in the Dictionary Catalogues of the Library of Congress (later to be titled Library of Congress Subject Headings) originally issued in parts, and was completed in March 1914.
Throughout its history, LCSH has been a dynamic system, growing with each edition, prompt in accommodating new topics.
Since the mid-1980s, in order to ensure the usefulness of LCSH to the library community at large, LC invited outside libraries to contribute headings to the system; more than 125 libraries worldwide now do this through SACO, the Subject Authority Cooperative Program.
Currently contains slightly more than a quarter-million terms.
LCSH Principles
User-centered Based on literary warrant and LC's
collections - Catalogers examine what is written, the terminology in use and the context in which the terms appear, and expect to demonstrate that a word or term is in general use in order to establish literary warrant.
Contains uniform and unique headings Provides direct access to specific subjects Assures stability and consistency, subject
headings need to be consistent Use the most specific subject heading that
can be found
