Cataloging books After the books are accessioned, classified, author-numbered or book-marked, and shelf-listed, they should be cataloged.

A catalog is a labor-saving device in library work.

From it both reader and attendant can ascertain whether the library has a certain book.

By consulting the catalog for the class-number, the book may be looked for in its proper place, thus often saving hunting through the shelves in several classes.
A printed list or catalog of the library is one of the first things that will be asked for by the public.

It is useful especially for those who cannot well visit the library.
