[203] I choose examples from the first fascicle. The later fascicles do not rise above it in quality. Among general works on bibliography (pp. 3-4) the authors should have mentioned John Ferguson (see above, pp. 110-111) and David Murray, "Bibliography: its scope and method with a view of the work of a local bibliographical society," _Records of the Glasgow Bibliographical Society_, I (1912-1913), 1-105. [204] Durey de Noinville might have been omitted. [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 Olga Pinto, _Repertori bibliografici nazionali_ is a reprint from a journal and has been replaced by _Le bibliografie nazionali_ (Milan, 1935), which is now in turn replaced by a second edition.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.
