College and Research Libraries tainly times when that risk is worth run- ning.—John J. Lund, Duke University Library. Philadelphia Libraries and Their Hold- ings; Data Compiled as Part of a Re- port on Philadelphia Libraries to the Carnegie Corporation of New York. Bibliographical Planning Committee of Philadelphia. University of Pennsyl- vania Press, 1941. pi., 46p. 50^. T H E TOOLS of library cooperation are of two kinds, the line-and-reel variety and the net. If you are after one book at a time, the union catalog, Union List of Serials, or catalog of a library or a collec- tion may land it for you. If, on the other hand, you seek all or much of the informa- tion on some topic, the mesh of any de- scription of library resources is likely to seem too fine or too coarse. Moreover, with this sort of purpose you are apt to need the aid of someone skilled in tracking through the ramifications of print to the sources you require and consequently may find that a printed guide to library re- sources omits an essential factor of the bibliographical process, the names of li- brarians or experts w h o know how to manipulate the literature in your field. Descriptions of resources are a poor sub- stitute for the organization of staff and book stock resources of the nation as a whole or of one of its subdivisions; but they are nevertheless a substitute which, in the hands of a resourceful librarian or a pertinacious student, will in the end help to connect print with the client. T h e Bibliographical Planning Commit- tee has compiled this list of special collec- tions and fields of specialization primarily as a guide for library planning, and has published it as a reference tool for li- brarians in Philadelphia and elsewhere. Since the list is a summary of the com- mittee's resources-information file (mainly supplied by the libraries described), this particular list is not a substitute for a bibliographical center, since the commit- tee is at present organizing one, but is one of the center's tools in handy form. As such, it gives librarians and scholars outside Philadelphia a rapid but not hasty survey of the Philadelphia library-stock situation. T h e major portion of the pamphlet contains abstracts of the de- scriptions on file arranged by broad classes. T h i s arrangement, though not novel to this type of publication as the introduction claims, is obviously a good one for plan- ning, since it shows gaps in subject fields which are covered, thinly presumably, only by general collections, and shows points of concentration at which the checking of bibliographies would indicate the need for coordinated purchasing. T h e abstracts are concise, seldom quantitative, occasionally vague, but their references to published inventories and catalogs, and the fact that more information is on file, make the list a useful tool for directing searchers in Philadelphia, a useful addition to the scat- tered resources-literature of the country at large. T h i s section is a portrait—and a handsome one!—of Philadelphia library resources. T h e rest of the pamphlet consists of recent (apparently 1939) book stock and expenditure figures for 31 libraries and departments; a chronology of Philadelphia libraries to 1900; and a classified list by subject specialization of libraries and de- partments. A good deal of hard clerical work has gone into the whole compilation, and in some places excellent professional work, such as the list of document collec- tions; there are one or two oversights, such as the omission of periodicals while JUNE, 1941 253 newspaper files and public documents are included, but this is not a piece of research — i t is a survey of the Philadelphia book stock, and as such an interesting and provocative work for non-Philadelphians. —John VanMahj A.L.A.

I F , AS P O P E P U T S I T , "Index learning turns no student pale, yet holds the eel of science by the tail" the editors of the Review Index have done their profession a service in providing another grip on those elusive appraisals of current books which librarians seek for their own ad- vantage and that of their patrons. I t is no substitute for the Book Review Digest because it gives no excerpts from reviews nor does it offer any symbols to indicate merit or the lack of it. F u r t h e r - more, it is a straight author list with no entries under subject or title and a mini- mum number of cross references. I t gives the author's name in secondary fullness, a brief title, publisher, date, price, and, as a rule, a reference to one book review, al- though occasionally a second or even a third is cited. W h i l e the Book Review Digest selects reviews of books more or less in the pub- lic eye from approximately 80 periodicals and newspapers, the Review Index lists all of the reviews, with a very few excep- tions, in about 60 journals of a scholarly kind, and covers nearly 400 more titles than the other index in a three months period. As might be expected, there is some overlapping. Of the items in a single column of the new index, 11 out of 31 titles were covered in the Book Review Digest, while of the 19 reviews of books in the September, 1940, issue of the Geographical Journal, 8 were included in both places. I t seems fair to conclude that the Review Index will provide each year critical information on about 1500 more books than has been available in the past. O n e is struck by the absence of the foreign reviews which are so greatly de- sired by research workers in certain fields. T h e Bibliographie der Rezenzionen, which will continue to appear, one hopes, covers the foreign field quite comprehensively but scholars and library staff shy away from it. W e like our information to come more easily. In any case, it is non- existent for the period covered by the Review Index. Foreign reviews are needed now as never before since personal communications with Europe have almost ceased. D u r i n g the latter part of 1940 few periodicals were received from con- tinental Europe. T h e y have begun to come again. Among important reviewing media seen during the past month have been: Beiblatt zur Anglia, Deutsche Rundschau, Zeitschrift fur Franzosische Sprache und Literatur and Nordisk Tid- skrift, to mention but a few of many. Incidentally, an important foreign lan- guage journal published in this hemisphere but omitted from the Review Index is Revista Iberoamericana which contains valuable signed reviews. Among English language periodicals there are several im- portant ones which are missing but they will most probably be added as a demand for them arises. W h i l e one misses any subject approach to material it is undoubtedly true, as the editors explain in the preface to the first 254 COLLEGE AND RESEARCH LIBRARIES
