Classifying books
The smallest public library should be classified and cataloged. This
will make its resources more easily available, and will prevent the
confusion and waste of labor which are sure to come if systematic
treatment of the books is deferred. Get the best advice obtainable;
consider the library's field and its possibilities of growth, and
let the first work on the books be such as will never need to be done
over.
To classify books is to place them in groups, each group including,
as nearly as may be, all the books treating of a given subject, for
instance, geology; or all the books, on whatever subject, cast in a
particular form--for instance, poetry; or all the books having to do
with a particular period of time--for instance, the middle ages. Few
books are devoted exclusively to one subject and belong absolutely
in any one class. The classification of books must be a continual
compromise. Its purpose is not accurately to classify all printed
things, this can't be done; but simply to make certain sources of
information--books--more available. Any classification, if it gets the
books on a given subject side by side, and those on allied subjects
near one another, is a good one.
Books may be classified into groups in a catalog or list, yet
themselves stand without order on the shelves. For convenience in
getting for anyone all the books on a given subject, and especially
for the help of those who are permitted to visit the shelves, all
books should stand in their appropriate classes. Each book, therefore,
should bear a mark which will tell in what class it belongs;
distinguish it from all other books in that class; show where it
stands on the shelves among its fellows of the same class; and
indicate which one it is of several possible copies of the same book.
This mark can be used to designate the book in all records of it,
instead of the larger entry of its author and title.
There are two classification systems worthy of consideration, the
Dewey, or decimal, and the Cutter, or expansive. They are outlined in
the following chapters. Don't try to devise a system of your own.
Having decided on your system of classification, begin to classify.
This is one of the many things which can only be learned by doing.
Give fiction no class number, but an author number or "book-mark"
only, as explained in a later chapter. Give all biography a single
letter as its class number, and follow this by the author number.
Distinguish all juvenile books, whether fiction or other, by writing
before their numbers some distinguishing symbol.
Take up first, in classification proper, the subjects of history and
travel, which will be found comparatively easy.
It is easier to classify 25 or 50 books at a time in any given class
than it is to classify them singly as you come to them in the midst
of books of other classes. Consequently, group your books roughly into
classes before you begin work on them.
As soon as a book is classified enter it at once in your
shelf-list--explained in a later chapter--and see that an author-card
for it is put in the author catalog--explained later--with its proper
number thereon.
If, after you have made up your mind, from an examination of the
title-page, or table of contents, or a few pages here and there, what
subject a book treats of in the main, you are still in doubt in what
class to place it, consider what kind of readers will be likely to ask
for it, and in what class they will be likely to look for it, and put
it into that class. In doubtful cases the catalogs of other libraries
are often good guides.
Keep your classification as consistent as possible. Before putting a
book, about which there is any opportunity for choice, in the class
you have selected for it, examine your shelf-list and see that the
books already there are of like nature with it.
Classify as well as you can, and don't worry if you find you have made
errors. There are always errors. Don't get into the habit of changing.
Be consistent in classifying, and stick by what you have done.
