This is a new and completely revised edition of a very useful volume. Various chapters are written by librarians who are especially well qualified in specific fields. The first 300 pages deal with such diverse subjects as early medical libraries and their literature; distribution of medical libraries and size of their collections; techniques of administration, acquisitions, cataloging, and classification; photoduplication methods; public relations; and rare books and the history of medicine. The remaining 200 pages contain a comprehensive bibliography of books in medicine and the allied sciences, both English and foreign titles, arranged by subject and carefully annotated. An excellent index adds to the usefulness of a book that seems almost indispensable in any field of medical library work, though it is not a book that would be of real value to physicians directly or personally.
