The _Anmerkungen zu den Kinder- und Hausmärchen der Brüder Grimm_ (5 v.; Leipzig, 1913-1932) by Johannes Bolte and Georg Polívka is a bibliography of parallels to the _Household Tales_. Some details in Besterman's work call for comment or correction, but their number is negligible in view of the vast number of titles with which he deals. There are instances in which I should disagree with him in the classification of titles. For example, the Augsburg library catalogue of 1600 (col. 626) is not a bibliography of classical literature but a general catalogue of books and manuscripts in the Augsburg municipal library. Furthermore, its inclusion contradicts the principle stated in the Introduction (I, p. xiv) according to which general catalogues of institutional libraries are omitted. J. B. Mencken's _Gelehrten-Lexicon_ with the second and third editions by C. G. Jöcher is cited (col. 331) as a universal bibliography, but Jöcher's later and much larger revision with its continuations is cited (col. 343) in a different category as a select universal bibliography. Errors in names, place names, and dates appear to be very few. I note that Thomas Cremius (col. 340) should be Thomas Crenius. Such details scarcely call for comment, and their lack of importance is itself a characterization of Besterman's skill. I could wish that the Preface to volume III had explained at greater length the alphabetization of anonymous titles beginning with such words as "Catalogue" or "Index." For example, I cannot find the _International Catalogue of Scientific Literature_ in the Index, although Section N for Zoology is cited in col. 3188. Nor is the _International Catalogue_ in the article "Science" (cols. 2725-2749), where a _List of Journals_ connected with it is cited (col. 2727).
