The bibliographical portion (pp. 403-758) of Thomas Hartwell Horne (1780-1862), _An Introduction to the Study of Bibliography_ (1814) is mentioned here only because Pie Namur, the author of a bibliography of bibliographies next to be discussed, names it along with A. F. Delandine's "Bibliographie spéciale" and Peignot's _Répertoire_ as a predecessor. Like other writers of handbooks of bibliography, Horne cites bibliographies without aiming at completeness. Horne's Part III, "A Notice of the Principal Works, Extant on Literary History in General, and on Bibliography in Particular," gives the information that it promises but contains no subject bibliographies and therefore cannot be called a general bibliography of bibliographies. It contains a brief account of "Dictionaries of Literary History" or works that we would call universal biobibliographies (pp. 403-408). The interesting survey of "Treatises, &c. on Literary History" (pp. 408-418) includes G. M. König, _Bibliotheca vetus et nova_ (1678) and J. P. Niceron, _Mémoires pour servir à l'histoire des hommes illustres dans la république des lettres_ (43 v.; 1726-1745) that should have appeared in the preceding section and two histories of philosophy for which his plan had no place. "Writers on British Literary History" (pp. 419-431) and "Writers on Foreign Literary History" (pp. 431-447) are accounts of national biobibliographies, histories, and bibliographies of literature, and of specialized biobibliographical writings. One finds in them occasional titles of infrequent occurrence like Christopher Wordsworth, _Ecclesiastical Biography, or Lives of eminent men connected with the history of religion in England, from the commencement of the Reformation to the Revolution_ (6 v.; London, 1810) or Giovanni Agostini, _Notizie istorico-scritiche intorno la vita e le opere degli scrittori Vineziani_ (2 v.; Venice, 1752). His rather full account of British works has some value but his incomplete foreign list is noteworthy chiefly for such curiosities as Matthias Bellus, _Exercitatio de vetere litteratura Hunno-Scythica_ (pp. 433-434) or Giambattista Toderini, _Della letteratura turchesa_ (p. 447). Horne devotes the following sections to writers on the materials used in writing and printing (pp. 448-450), writers on the origin of languages, letters, and writing (pp. 451-469), and writers on the history and the art of printing (pp. 469-513). A strictly bibliographical "Chapter IV. Books" (pp. 513-550) contains books on bibliomania, handbooks of bibliography, catalogues of rare books and incunabula, dictionaries of anonyma and pseudonyma, and lists of burned, suppressed, or censured books. The most valuable part of Horne's _Introduction_ is the fifth chapter, on bibliographical systems and catalogues. The account of bibliographical systems (pp. 551-563) is not very important, but the review of British and foreign public and private library catalogues (pp. 564-733) has not been entirely superseded.
