In most leather bindings the back is divided into five or six panels, making it possible to obtain uniformity by setting aside each panel for a definite purpose. If desired, another narrow panel may be made in which to stamp a mark of ownership. Paneling is a useful device in the case of books which are eight inches or more in height, but in the case of juvenile books and fiction it may be omitted entirely. As most of these books require simply author, title and call number, if one be used, the device of paneling adds to the labor in binding and serves no useful purpose in the library. It should be used on most other books bound in leather and on all periodicals bound in cloth or duck.

Which shall go at the top of the book, author or title? In favor of the title it can be claimed that all publishers letter the title first with the author second; and since in non-fiction the books in publishers' covers on the shelves will outnumber the rebound books, it is advisable to put the title first in order to have uniformity. On the other hand, it can be claimed that the arrangement under the class is by author, that most library assistants look for the author rather than the title, and that it is therefore advisable to put the most important item of information at the top in the position of greatest prominence. In the opinion of the writer this advantage outweighs any other.

It may be assumed, therefore, that the best arrangement is author, title, volume number if necessary, and call number. In the case of fiction, juvenile books and all other books from which it seems desirable to omit panels, these items will be put on with sufficient space between to make them independent of each other. The bottom of the call number should be 1-1/4 or 1-1/2 inches from the tail of the book on all books in the library, except oversized books, which should have the call number at the top (Fig. 16). If panels are used, the author's name should be near the bottom of the first panel, the title in the second, volume number in the fourth and call number in the fifth (Fig. 15).

If two books are bound together, letter, author and title of the second book in the third panel (Fig. 17).

When a work is in more than one volume with separate titles for each volume, place the author's name in the first panel, general title in the second, volume in the third and the title of the particular volume in the fourth (Fig. 18).

If six panels are used, each item is dropped one panel.

In most cases the author's last name is sufficient, but occasionally it may be necessary to use initials to distinguish between authors having the same name. Use both surnames of joint authors (Fig. 19). For pseudonyms use the form adopted by the cataloging department. For example, if the catalog entry is under Clemens instead of Twain, letter Clemens on the book. Both real name and pseudonym may be put on the back, but it does not seem necessary. In the case of the classics add the name of translator or editor in the panel under the title (Fig. 20).

When the names of foreign cities or countries must be placed in the author panel, use the English form. Names of government departments, bureaus, etc., should be inverted if necessary to bring the distinctive word first. For example, use Health bureau, not Bureau of health.
