INSTRUCTIONS TO THE BINDER
Having decided that the volume must be bound and having arranged it in its proper order, the next step is to indicate to the binder how it is to be bound and lettered. Various methods have been used to indicate style and lettering. Some libraries have an elaborate binding slip, giving on one side the different materials, colors, etc., and having the other divided into panels for lettering. A slip is made for each book and the binder follows it carefully. Some libraries arrange an arbitrary system with the binder making one letter or figure indicate much that otherwise would have to be written in full. For example, "C" under such an arrangement might mean "Bind in one-half red cowhide with green cloth sides." Some librarians give a general blanket order to bind all fiction in one way and all juvenile books in another.
For most books in English, except periodicals, lettering need not be indicated on a binding slip. All that is necessary is to underscore lightly on the title page the first letter of words which must be used. The call number may be put on a binding slip enclosed in the book, or in the case of fiction and juvenile books, it may be penciled lightly on the title page, thus doing away altogether with the binding slip. If there is a chance for misunderstanding on the part of the finisher, or if an author's real name must be used instead of a pseudonym which appears on the title page, a binding slip must be filled out giving exact lettering.
While exact lettering on a binding slip is not essential for ordinary books, it is necessary for periodicals, each set of which should be bound and lettered uniformly. This may be assured by making out a binding slip giving in full the title, dates covered, volume number and call number, if one is used. The slip goes to the bindery with the book, and when the volume is returned is filed so that when the next volume is to be bound the slip can be consulted and a new one written with the necessary changes in volume number and dates. The chief value of the slip is to show exactly how the previous volume has been bound, so that the following volumes can be made uniform if possible.
A carbon copy of binding slips for periodicals should be made, to be kept at the library for charging purposes.
When binding volumes which are a part of a set, other than a periodical, a slip must be made to be kept on file so that when another volume of the set comes to hand it will not be necessary to visit the shelves to see whether other volumes have been bound and how they have been bound.
In finishing periodicals the position of lettering and the size of type used may be kept uniform if the binder takes what is called a "rub" or "rub-off" of the book after it is lettered and keeps it on file at the bindery. This can easily be made by laying a sheet of thin, but tough, paper over the back and rubbing it with shoemaker's heel-ball which will show white lettering on a black background. When the next volume comes to the bindery the "rub-off" shows exact height of boards, exact position of lettering and size of type.
A few libraries have had a dummy back made for each periodical showing color and kind of material in addition to other details. But the cost of a dummy is not slight and a new one must be made whenever any change in title or size occurs. Large college or reference libraries may need dummy backs for their numerous sets of foreign periodicals having various marks, such as umlauts, etc., over or under letters. When a library operates its own bindery it is possible to send the last bound volume as a sample. While this adds much to the routine, its main advantage is that it eliminates the possibility of mistakes due to defective dummy or indistinct "rub-off."
