Cataloging and Classification is also a name for the course that covers general principles of bibliography, cataloging, and indexing, that is required for students working toward degrees in Library/Information Science. Of the few texts available for the course, Lois Chan's Cataloging and Classification is the best because the author is the most widely known and respected authority in the field and the text contains complex, difficult information that is presented clearly and in an organized understandable manner, and provides exercises to reinforce the concepts.
