Although far from complete, it contains information not easily found elsewhere. It resembles Peignot's similar review, on which Horne has drawn heavily. He concludes with a brief survey of publishers' catalogues (pp. 733-741), references (pp. 741-742) to two of Peignot's bibliographies that he believes to be adequate guides to subject bibliography, and addenda (pp. 743-758). Horne did not intend his _Introduction_ to be a bibliography of bibliographies and we need say no more about it. A "Bibliographie spéciale et chronologique des principaux ouvrages sur l'imprimerie et la bibliologie" by Antoine François Delandine (1756-1820) is printed in his _Bibliothèque de Lyons_ (Paris, 1816). I have not seen Delandine's original list but have used a later and slightly enlarged version. In this, Etienne Psaume has, according to Namur, added a few books printed between 1812 and 1822 and the new title "Appendice de l'Essai sur la bibliologie" (1824). This, is an annotated chronological list of nearly three hundred and fifty books on the history of printing, catalogues of public and private libraries, and bibliographies of miscellaneous scope. This somewhat casual performance is useful at best for a few curious or informative notes. The bibliographies do not amount to many more than a hundred and do not offer either in number or variety a satisfactory survey of bibliography. A selection of good catalogues of private libraries (chiefly French) is the best feature of the "Appendice." The distressingly careless citations show that the compilers did not see some of the books. This list shows some originality and is worth reading, but it deserves no significant place in the history of bibliographies of bibliographies.
