She must examine the books carefully, studying the table of contents, preface, analyses of chapters when given, marginal notes, and the chapters themselves when necessary. No entry is to be made under any subject unless the cataloger is sure that the book contains material helpful to one looking up that subject. She must always try to put herself in the reader’s place, and get his point of view.

The cataloger is extremely liable to worship rules and to forget the limitations of the average reader. There is danger of taking too much for granted. In this respect the cataloger is like a certain professor who was given to quoting Arabic in his popular lectures. When some one, remonstrated, he said, “Oh, everybody knows a little Arabic.”

The cataloger must bear in mind the fact that many users of the library do not know how to look up book titles. President Eliot once confessed to a body of librarians that although he might claim to be as intelligent as the ordinary frequenter of a library, he did not know enough to use a card catalog.

Cutter’s Rules.—Having decided what the subject or subjects of the book may be, for it may have one or many, the question arises as to the form of the subject headings to be used. C. A. Cutter, in his “Rules for a dictionary catalog” (4th edition, 1904) has laid down the principles of the choice of subject headings. One of the most useful tools of the cataloger is the American Library Association “List of subject headings” (3d edition, 1911), the result of widespread consultation and discussion on principles and practice. Here is gathered the experience of many libraries, of all types, and the cataloger would do well to follow this list unless experience has shown her that in some cases her special library requires a variation. The suggested cross references are a great help, but must be used with care and judgment. The cross references are the sign posts in the wilderness of the catalog, and they must point the way clearly and with truth. The cataloger never knows at just what point the reader will strike the catalog, but if the subject headings and cross references have been judiciously chosen he is pretty sure to reach the desired goal.

Analyticals.—In a small library it is most essential to show not only what books the library has on a given subject, but also what chapters or essays may be hidden in unsuspected volumes. Entries for such parts of books are called analytical entries. The subject heading is chosen in the same manner as for an entire work on the subject, the author, title, date, call number and paging of the volume containing the chapter being given below the subject heading. In similar manner author and title analytical entries may be made for short stories which appear in collections. Author analytical entries are frequently needed for collections of essays, etc.

Form of Card.—The form of the card is of minor importance, provided it is clear and gives all of the important information. It is well to make prominent the author’s name by indention. The title must omit nothing which will aid the reader in his choice of a book. The name or number of edition and the name of the editor or translator should be included. Names of illustrators may be omitted unless they are of sufficient importance to require an added entry card. In a public library added entries under the names of popular illustrators like C. D. Gibson, Joseph Pennell or Walter Crane, will often prove helpful.

Imprint and Collation.—Fullness of imprint and collation varies in different libraries. The cataloger should not count on the library always remaining very small, but should include enough details of imprint and collation to assure her that the cards will be useful when the library has grown. The A. L. A. rules give detailed instruction for imprint and collation, while any of the papers written on cataloging for the small library will point out the possibilities of simplification.

Contents Notes.—The contents of the book should be given whenever it will add important items to the reader’s knowledge of the book. Descriptive and critical notes will often tell a reader positively whether or not he wishes the book, when the title alone could not do this.

Subject headings for historical fiction—and also for poetry and drama—will be found most helpful. Thus Winston Churchill’s “Crisis” can well have an entry under U. S. History—Civil War—Fiction, and Dumas’ The Whites and the Blues, an entry under Napoleon I—Fiction.

Printed Cards.—The use of the Library of Congress cards will be found a great labor saver. If, at the time of ordering the cards, a temporary slip bearing call number, author, title, place and date of publication, accession number and suggested subjects and analyticals be written, a second examination of the book on the receipt of the cards will be unnecessary, unless the cards disagree with the book in some of the data noted. The Library of Congress, on application, will send instructions for the ordering of cards. Although it is cheaper to order cards by serial numbers, it will not pay the cataloger to spend much time searching for this number as for 1/2c per title the Library of Congress will do this work. The use of the printed cards, though it will destroy the uniformity of appearance of the catalog, will in no way detract from its usefulness or usableness.
