A serious criticism of Petzholdt's plan concerns the inclusion of bibliographies, which (although pertinent) can be easily found and might have been dealt with briefly. The bibliography of individuals "Personale Literatur," (pp. 156-272) is a branch of bibliography and must therefore be included. Nevertheless, few bibliographies are more easily found than lists of an author's works. The great biobibliographical dictionaries from Conrad Gesner's _Bibliotheca universalis_ of 1545 down to the various editions of the _Biographie universelle_ and the _Nouvelle biographie universelle_ contain this information. Biographies, wherever published, ordinarily contain bibliographies of the books written by the author in question. There are excellent indexes of these biographies. Antoine Teissier had added, in his _Catalogus_ and _Auctuarium_, some two thousand biographies to Labbé's _Bibliotheca bibliothecarum_. E. M. Oettinger had just published two editions of the _Bibliographie bibliographique universelle_,[150] which is still a very convenient and full list of biographies. Any good edition of a classical text is almost certain to contain bibliographical information, and scarcely needs to be cited in a bibliography of bibliographies.[151] He could have written an entirely adequate bibliography of bibliographies of individuals in much less than a hundred and sixteen pages. He might, for example, have omitted the bibliography of R. Salomo b. Abraham b. Adereth (p. 166)--I cite the first name in his list--that is found in a biography of this worthy and the bibliography of Martial (p. 226) that is found in an edition of his works. Such omissions would not have impaired his book and would have substantially reduced its bulk.
