In spite of its brave title, _Internationale Bibliographie der Bibliographien_ (1939-1950), this book by Hanns Bohatta (1864-1950), Walter Funke, and Franz Hodes belongs on the level of bibliographies by Durey de Noinville and Michael de San José. It will only rarely aid either the beginner or the more advanced scholar. It is a selective bibliography and the choice of titles will satisfy no one. Obvious books are lacking[203] and worthless compilations are present.[204] The authors pay little attention to the categories that they set up.[205] The references are incomplete and inaccurate.[206] The comments are often misleading or erroneous. For example, the remark that Giuseppe Fumagalli, _La bibliografia_, is much less complete than Giuseppe Ottino and Giuseppe Fumagalli, _Biblioteca bibliografica italiana_, is a fundamental misapprehension of both works. The first is a handbook of general bibliography; the second is a bibliography of bibliographies written in Italian or concerned with Italy. The second book belongs elsewhere and the supplements to it should be cited at length because they were written, in part, by other authors. A comparison of the two books is without point. With all its faults this disorderly _Internationale Bibliographie der Bibliographien_ yields useful information.[207] The most ambitious and the best of these four modern selective bibliographies is L.-N. Malclès, _Les Sources du travail bibliographique_, I (Geneva, 1950). This deals with general works and cites almost exclusively bibliographies. A second volume (2 pts., Geneva, 1952), which deals with the humanities, has recently appeared. A third volume, which will deal with the sciences, is promised. An abbreviated edition has been published even though volume 3 has not yet been issued. Both the second and the promised third volume are subject bibliographies and therefore need no mention here. The first volume contains some information about books that are not bibliographies, although they are somewhat similar in nature to bibliographies. There is, for example, a very interesting chapter on encyclopedias (pp. 213-224) and another chapter (pp. 225-237) on collective biographies. The wholly practical spirit of Mlle. Malclès's endeavor appears clearly in her list of German encyclopedias. She is right in thinking that a modern worker will rarely look at a German encyclopedia older than Ersch and Gruber ("1818-1889, 97 vol. 4^o [A-Z]"). The reference is, incidentally, not quite accurate, since large portions of the alphabet were never written. We hear nothing of the early German encyclopedist J. H. Alsted, who lived and wrote two generations before Louis Moréri (he is mentioned as the first French author of an encyclopedia on p. 219), or of Krünitz and Zedler, who wrote vast encyclopedias almost two centuries ago. Such German works are not appropriate to Mlle. Malclès's purpose, but their absence means that her book does not
