College and Research Libraries items useful to the classifier). Form divisions are given seven pages of attention, but the need is felt for even more elaboration on the use of these all-pervasive "floating ta- bles." Complete absence of any graphic aids to DC is everywhere apparent, but especially in this section, which would benefit from tabular display. At scattered spots, order of preference is recorded (e.g., at Form Divi- sions A and Form Divisions 061-063 A). The provision of a precedence table, comparing 'all possible pairs of numbers would give more clarity at a glance than is now possible. There is need for check lists of questions the classifier should ask as each number is built: (Is the basic number more than five digits long? If so, see Form Division F (1). If not, continue.) That the Decimal Classifica- tion Office does recognize the utility of se- quential instruction is apparent in Gen- eral Principles and Procedures XA (Number Building), which gives a five-step procedure for preventing "divide like" instructions from going sour. To examine this book outside its universe might yield as unsubstantial results as the re- view of a telephone directory which found it to be strong in its characters but weak in plot. It might be worthwhile, however, to emphasize the attitude revealed by the title. This work is not a guide to use of DC by readers. It is instead, as we take for granted, a guide to use by classifiers. Godfrey Dewey, in his preface, specifically points to "the classifier, the user of the classification." The book describes the input operations to the system, but concerns itself little, if at all, with any eventual output requirements. Only by accepting this inner perspective can the practices of the Guide be viewed as neces- sarily practical. But the world at large and nonlibrarians in particular refuse to abide by this rule. They will judge the practices and the Guide according to the facility or limitation it offers on their ability to find books. A basic limitation is the subordination of geographical to subject aspects, when an area program wishes to collect subject in- formation relating to a given area. Each of us must make two separate evaluations of this book: first, how well it has accomplished what it set out to do, and second, what ef- fect it will have when we put it into practice. The answers may be a world apart.-Earl Farley~ University of Kansas Libraries. JANUARY 1963 Science Bibliography American Scientific Books 1960-1962. Ed. by Phyllis B. Steckler. 'New York: Bowker, 1962. 474p. $10. Every librarian with an interest in scien- tific and technical books will want to own, or have ready access to, at least one copy of this handy bibliography which contains a wealth of information on some eight thou- sand selected entries cumulated from the monthly issues of the American Book Pub- lishing Record (] anuary 1960 to March 1962). This, according to the publisher, marks the first cumulation in any subject area from the well-known Bowker publica- tion. Entries are arranged principally by Dewey Decimal classification headings. The form of entry, in general, follows that used by the Library of Congress for its catalog cards and includes author, title, publisher, price, and catalog card number. In addition, brief de- scriptive annotations are included with many of the entries. Author and title indexes also are provided. Some fastidious individuals will find the title of this bibliography to be in slight dis- agreement with the actual content. For, in fact, the ·books are not all American (books written by foreign authors and printed abroad but offered for sale in this country through a single designated agent are in- cluded) , titles included are not all scien- tific (a majority of the books would be classed as medical and technical), items other than books are listed (several small pamphlets and other nonbook materials are included), and finally, the majority of the books appear to have been published in 1959-1961. It would serve no useful purpose to refer in detail to each of the minor errors or mis- prints noted. In a few cases the prices given are not current, but the differences are slight and of little consequence. In spite of the fact that this bibliography contains no information that was not previ- ously available, the very convenience of this cumulation will make the volume a valuable addition to the reference bookshelf.-John Sherrod, Science and Technology Division, Library of Congress. • • 79
