_Bibliothecae Cordesianae Catalogus, cum indice titulorum_, Parisiis, 1643, 4to. The celebrated Naude had the drawing up and publishing of this catalogue, which is highly coveted by collectors, and is now of rare occurrence. De Cordes was intimate with all the learned men of his country and age; and his eulogy, by Naude, prefixed to the catalogue, gives us a delightful account of an amiable and learned man living in the bosom, as it were, of books and of book-society. This collection, which was purchased by Cardinal Mazarin, formed the foundation of the latter's magnificent library. Consult the _Jugemens des Savans_, vol. ii., p. 142; Colomie's _Biblioth. Choisie_, p. 126; _Mem. de l'Inst._, vol. i., p. 647. Nor must we forget Morhof--_Polyhist. Literar._, vol. i., p. 211; who, after a general commendation of the collection, tells us it is remarkable for containing a fine body of foreign history. De Cordes died A.D. 1642, in the 72d year of his age--nearly 50 years having been devoted by him to the formation of his library. "Fortunate senex!"----COTTE. _Catalogue des Livres rares et precieux et de MSS. composant la bibliotheque de M---- (le President de Cotte)_, Paris, 1804, 8vo. We are told by Peignot that the books at this sale were sold for most exorbitant sums: "the wealthy amateurs striving to make themselves masters of the LARGE PAPER Alduses, Elzevirs, and Stephenses, which had been Count d'Hoym's copies." An uncut first edition of Homer, in the highest state of preservation, was purchased by Mons. Caillaird [Transcriber's Note: Caillard] for 3,601 livres! See the _Curiosites Bibliographiques_, pp. lxv, lxvj. According to _Cat. de Caillard_, no. 2600 (1808, 8vo.), there were only ten copies of this catalogue printed upon LARGE PAPER.----COUVAY. _Catalogue de la bibliotheque de M. Couvay, chevalier de l'ordre de Christ, secretaire du Roi_, Paris, 1728, fol. Very few copies of this catalogue were printed, and those only for presents. _Bibliogr. Curieuse_, p. 21.----CREVENNA. _Catalogue raisonnee de la collection des Livres de M. Pierre Antoine Crevenna, Negocient a Amsterdam_, 1776, 4to., six vols.--_De la meme collection_, 1789, 8vo., five vols.--_De la meme collection_, 1793, 8vo. Of these catalogues of one of the most extensive and magnificent collections ever formed in Amsterdam, the first impression of 1776 (to which I have generally referred) is by far the most valuable in regard to bibliographical remarks and copious description. Peignot tells us that no bibliographer can do without it. It was commenced in the year 1774, and published during the life time of Peter Antony Crevenna, the father; from whom the collection passed into the hands of the son Bolongari Crevenna, and in whose
