The limits of this sketch will not permit even a summary of the long list of books issued by the Elzevirs during this century in which they were doing business as publishers. It is only practicable to refer to the general character of these publications and to point out that they included the most considerable and comprehensive series of important literature that had been associated with any imprint since the invention of printing, while it is also in order to remember that a very large proportion of the volumes represented the highest development of the art of typography. After two centuries of competition, the country of Koster had, in the work of the printing-press, unquestionably outclassed the country of Gutenberg and the rest of the world. The publishing career of Louis Elzevir, the founder of the House, continued from 1583 to 1617, a period of thirty-four years. During this term he published a hundred and one separate works. His first book, the work which initiated the publishing undertakings of the Elzevirs, bears the title: “Drusii Ebraicarum quæstrinum, sive quæstrinum æ responsionum, libri duo, videlicet secondus œ tertrus. In Academia Lugdunensi.” 8vo. 1582 The following were the more noteworthy of the later publications of Louis: “Chronique et Histoire Universelle,” etc., “Par Jean Carion, Ph. Melanchthon, et Gaspar Pencer,” 2 vols., 8vo. 1596 This was the first work printed in French by the Elzevirs. Sundry Treatises of Scaliger. A Memoir of Scaliger by Heinsius. 1607 The first work of an author whose name was to appear in the Elzevir lists more frequently than that of any other writer. Certain works of Aristotle, edited by Heinsius. 1609 The complete works of Horace, edited by Heinsius. 1612 The Essays of Heinsius. 1612 The Homilies of Heinsius. 1613 The Letters of Puteanus. 1614 A History of the Frisians, by Emmius. 1616 “The Catechism of the Reformed Church.” 1617 With a few exceptions in Dutch and in French, the works of Louis were printed in Latin. The greater number bear on their title-page the words _cum privilegio_. The privilege, when secured, was issued by the States-General, and the usual term was from ten to fifteen years. I find in the catalogue of titles no specification (such as was at this time usual in France) of an official censorship. The association of Matthew, Bonaventure, and Abraham Elzevir, who succeeded to the business of their father Louis, and with whom was associated as the printer to the concern their brother, Isaac Elzevir, continued from 1617 to 1625. During these seven years, they published one hundred and twenty-two separate works and editions. I specify certain of the more important:
