Abstract
The Library of Congress Subject Headings system, originally developed for the Library's own collection in the late nineteenth century, has been widely adopted and has been the de facto standard for subject cataloging in American libraries for nearly a century. Ironically, there has never been a written code to guide its initial formation or to direct its continuing development. Rules for descriptive cataloging have evolved through continuing efforts in revision. There are no comparable rules for subject cataloging. The concise book entitled Subject Headings: A Practical Guide (1951) by David Judson Haykin (1896-1958), Chief of the Subject Cataloging Division of the Library of Congress from 1941 to 1952, has come the closest to being an official pronouncement of the principles and practice of the Library of Congress Subject Headings system. The book offered a rationalization and an explanation of the Library of Congress practice as it was at the time. Many of the policies described in the book have since been changed, but the basic guidelines and principles set forth by Haykin are still valid today. The following excerpt is taken from the chapter entitled "Fundamental Concepts." Here, the influence of Charles A. Cutter's principles (q.v.) an the Library of Congress system is clearly discernible, although not officially acknowledged. The principles outlined by Haykin-focus an the user, the principle of uniform headings, the reliance an common usage, and the principle of specific and direct entry-echo those expounded by Cutter many years earlier. In his discussion of "the reader as the focus," Haykin reiterated Cutter's emphasis an the "convenience of the public" at the sacrifice of logic.
