[205] The category of bibliographies of bibliographies (pp. 3-4) includes bibliographical journals, general bibliographies, special bibliographies (which should have been put in later sections), and lists of medieval catalogues of libraries.
[206] For example, "J. B. Childs, Sixteenth-century books. Chicago, 1923" is inaccurate in details and lacks the essential information that it appeared in the Papers of the Bibliographical Society of America, XVII (1923), 73-152. Olga Pinto, Repertori bibliografici nazionali is a reprint from a journal and has been replaced by Le bibliografie nazionali (Milan, 1935), which is now in turn replaced by a second edition. The books by Alice B. Kroeger and Isadore G. Mudge are cited separately, but Miss Mudge's Guide to Reference Works is a revision of the earlier work. The earlier work need not have been mentioned.
[207] See references to an article on printed catalogues of Scotch libraries (p. 3), a Russian bibliography of library catalogues (p. 3), and several obscure studies of anonyma and pseudonyma (pp. 19-22).
[208] Bibliographies of bibliographies found in handbooks of library science and bibliographies of reference works (which may often be bibliographies) have not been included in this essay. There are good books of these kinds that might seem to have been overlooked. For example, Georg Schneider, Handbuch der Bibliographie (4th ed.; Leipzig, 1930) names only currently useful lists of books and no bibliographies of subjects. His account of the bibliographies of incunabula (pp. 85-103) is an excellent introduction to a difficult subject, but gives no idea of the historical development of these works and cites the earliest bibliographies (p. 92, n. 1) in such a way that only an expert can interpret the references. A good American parallel to Schneider's book is H. B. van Hoesen and F. K. Walter, Bibliography, practical, enumerative, historical: an introductory manual (New York, 1928); a new edition is in preparation. John Minto, Reference Books (2 v.; London, 1929-1931) and Constance M. Winchell, Guide to Reference Books (7th ed.; Chicago, 1951) are guides to reference books, not bibliographies of bibliographies, Frantz Calot and Georges Thomas, Guide practique de bibliographie (Paris, 1936; 2d ed., Paris, 1950) is often a helpful guide to information, but it is not a bibliography of bibliographies.
[209] The numbers refer to the edition of 1901.
[210] See especially Nos. 153-157. The section "Literatur und Miscellen" (No. 86) in the Neuer Anzeiger should have been listed under 1856, when the journal began, rather than under 1886, when it ceased to appear.
[211] Tosselli (No. 8) is Tonnelli. The description of F. Perennès, Dictionnaire de bibliographie catholique (No. 33) is incomplete.
[212] See his important article, "Petzholdt redivivus. Zur Theorie und Praxis eines allgemeinen internationalen Bibliographienverzeichnisses," Zentralblatt für Bibliothekswesen, LXIV (1950), 413-438.
