It is difficult to say much in praise of this compilation, which has, indeed, been universally condemned. Its general plan is basically wrong, and it contains far too many irrelevancies, mistakes, omissions, and second-hand descriptions. To indicate the general standard of accuracy maintained by Vallée, it is perhaps enough to say that, although a large part of his volume was taken bodily from Petzholdt, that scholar's name is spelt incorrectly throughout the entries under his name. Vallée's book is unsatisfactory, but I cannot listen to this chorus without examining the criticisms briefly. Josephson's damning notice signifies very little. As far as such rough tests as I have used can show, Vallée does not include an unreasonable proportion of unsuitable titles. I have examined the first entry on page 25, and each succeeding twenty-fifth page without finding an instance of a non-bibliographical title. If Josephson means that Vallée gives many unnecessary references, I should agree with him. Vallée should not choose to cite Thomas Stapleton's biography of Sir Thomas More (p. 519, No. 6048) because it contains bibliographical information or to give hundreds of similar references. I cannot however agree with Josephson's remark that Vallée fails to indicate where this bibliographical information appears in the books cited. It seems altogether unnecessary to cite a bibliography found in a biography, an edition of a classical Latin or Greek author, or a general treatise on some subject, but when Vallée cites it, as he does in imitation of Petzholdt with distressing frequency, he ordinarily gives reference to pages. I cannot see that an alphabetical arrangement according to authors with a subject index is very much more difficult to use than an alphabetical or classified arrangement according to subjects with an author index, but in this opinion I stand alone against general bibliographical practice and shall say no more here. In any event, Vallée's choice of arrangement seems a comparatively minor fault, when compared with Petzholdt's and Stein's choice of a classified arrangement with altogether unsatisfactory subject indexes and hastily-made author indexes. I speak in Vallée's behalf partly because of Josephson's arrangement of a bibliography to be mentioned at the end of this essay. Josephson chose to arrange the titles in chronological order without providing either an author or a subject index. No one has ever recommended such an arrangement.
