[Footnote 159: DE LA SERNA SANTANDER will always hold a distinguished place amongst bibliographers, not only from the care and attention with which he put forth the catalogue of his own books--the parting from which must have gone near to break his heart--but from his elegant and useful work entitled, "_Dictionnaire Bibliographique choisi du quinzieme Siecle_," 1805, &c., 8vo., in three parts or volumes. His summary of researches, upon the invention of printing, Mr. Edwards told me, he read "with complete satisfaction"--this occupies the first part or volume. The remaining volumes form a necessary, as well as brilliant, supplement to De Bure. Just at this moment, I believe that Mr. Beloe's, and my own, copy of the work, are the only ones in this country.----CAILLEAU has the credit of being author of the _Dictionnaire Bibliographique_, &c., in three volumes, octavo, 1790--of which there are a sufficient number of counterfeited and faulty re-impressions; but which, after all, in its original shape, edit. 1790, is not free from gross errors; however useful it is in many respects. I suspect, however, that the Abbe DUCLOS had the greater share in this publication: but, be this as it may, the fourth supplemental volume (by the younger Brunet) is, in every respect, a more accurate and valuable performance. OBERLIN, librarian of the central school or college at Strasbourg, is author of a bibliographical treatise particularly deserving of the antiquary's attention: namely, _Essai d'annales de la vie de Jean Gutenburg [Transcriber's Note: Gutenberg], &c._, Stasb. [Transcriber's Note: Strasb.], an. ix., 8vo. His other numerous (belles-lettres) works are minutely specified by Peignot in his _Dict. de Bibliologie_, vol. iii., p. 230. His edition of Horace, Argent., 1788, 4to., is both elegant and correct.]
