[151] I do not see what principle guides him in the choice of bibliographies published in the editions of an author's works. He does not include, for example, a very curious bibliography in Marcus Meibomius (ed.), Diogenes Laertius, _De vitis, dogmatibus et apophthegmatibus clarorum philosophorum_ (Amsterdam, 1692). It is the first bibliography, as far as I know, to give systematically the locations of the books cited. The first example of a reference to the place where a book may be found is, I believe, in Giovanni Nevizzano (Johannes Nevizzanus), _Quaestiones_ (ed. L. Gómez; Venice, 1525). I quote it from Wilhelm Fuchs, "Die Anfänge juristischer Fachbibliographie," _Archiv für Bibliographie, Buch- und Bibliothekswesen_, II (1929), 49. [152] See, for example, a list of men named Alard (p. 167). [153] "Petzholdt redivivus. Zur Theorie und Praxis eines allgemeinen internationalen Bibliographienverzeichnisses," _Zentralblatt für Bibliothekswesen_, LXIV (1950), 413-438. [154] I am of course aware that the _Guide to Reference Books_ originally written by Alice Kroeger has passed through many editions and has had two subsequent editors. Its well-deserved success is no very strong argument for the usefulness of a classified arrangement. The _Guide_ is, it must be recognized, a very special sort of reference work. It has been intended from the beginning to serve reference librarians and has been improved and enlarged for that use. In other words, it has always had very limited and highly trained readers familiar with its special methods. The latest edition is by Constance M. Winchell (7th ed.; Chicago, 1951). [155] _Prosopographia & heroum atque illustrium virorum totius Germaniae_ (Basel, 1656-1566); _Teutscher Nation Heldenbuch_ (Basel, 1567-1570). The two editions differ somewhat in contents. [156] Third ed.; Berlin, 1930, pp. 186-200. [157] Arnold Kuczynski, _Thesaurus libellorum reformationis illustrantium_ (Leipzig, 1870. ICN; MH. Supplement, 1874. MH); Oswald Weigel (comp.), _Bibliothek J. K. F. Knaake. Katalog der Sammlung von Reformationsschriften des Begründers der Weimarer Lutherausgabe_ (6 pts. and list of prices. Leipzig, 1908. DLC [6 pts.]; ICN [complete]; MH [pt. 1]). [158] These are, respectively: _Bücherschatz der deutschen National-Litteratur des XVI. und XVII. Jahrhunderts_ (Berlin, 1854. CU; MH); _Verzeichniss von Büchern vorzüglich aus der Freih. v. Meuse-bach'schen Bibliothek_ (2 v.; Berlin, 1855, 1856. CU; MH); Karl Faber und Emil Hirsch, _Sammlung Viktor Manheimer. Deutsche Barockliteratur von Opitz bis Brockes_ (Munich, 1927). The Prussian state library bought the Heyse and Meusebach collections. [159] Examples of catalogues used for such purposes are the _Bibliotheca Heberiana_ (13 pts.; London, 1834-1837. The thirteenth part was published in Brussels. ICN [pts. 1-12]); the Robert Hoe catalogue (5 v.; New York, 1911-1912); and the A. H. Huth catalogue (6 v.; London, 1911-1920).
