Excerpt from Guide to the Study and Use of Reference Books This manual is a guide, designed primarily to help library assistants, library school students, college students, teachers, and users Of libraries in general, in gaining a knowledge Of reference books quickly. It does not pretend to be complete. The reference books and bibliographies included in this list are necessarily limited, first, to those Of a strictly reference character, and, secondly, to the most useful works in the English language, with some exceptions in other lan guages. It is Obviously impossible, without exceeding the limits of one volume, to include all of the important works of reference in foreign languages, which, though Often Of more value than the corresponding English books, still are Of restricted use owing to the comparatively small number of readers Of foreign languages who frequent our libraries. Reference books which are limited to the use Of the specialist have been in like manner usu ally omitted. Out-of-print books have occasionally been mentioned because they are to be found in the Older libraries. It sometimes happens that the best reference book on a subject is out Of print. Almost all books Of reference possess defects as well as merits; it is difficult indeed to find one that is perfect. At the same time they are essential to a well-equipped library. The annotations Of the titles herein contained are largely of a descriptive character, showing for what purposes the books mentioned are especially useful. Besides cyclopedias and dictionaries which give direct aid, the reader will have to consult more elaborate treatises for further information. Bibliographies are guides to these. A know ledge Of bibliography, therefore, forms an important part in the preparation Of the student. The most useful reference department will include bibliographies of special subjects along with the cyclopedias Of those subjects. It is to be regretted that books belonging to the class Bibliography are as a mle kept in the cataloger's room or the librarian's Office, not in the reference department where they would be useful to the public. In a large library, such an important printed catalog as that Of the Peabody Institute Library and a bibliographical work like the United States catalog and supplement, should by all means be kept Where the public can have easy access to them even if it is necessary to duplicate such works.
