The latest edition of this classic work [formerly Immroth's Guide to the Library of Congress Classification (Libraries Unlimited, 1990)] provides you with a basic understanding of the ever-evolving Library of Congress Classification system and its applications. After introducing the classification and giving a brief history of its development, the author presents readers with the general principles, structure, and format of the scheme. She then discusses and illustrates the use of tables. In a chapter new to this edition, Chan provides a general discourse on assigning LC call numbers.
