Beughem, Cornelius De

, whose name often occurs in works of Bibliography, but who has not laid bibliographers under many obligations, was a bookseller at Emmerich, about the end of the seventeenth century. His design in his compilations was evidently to serve the cause of literature, but although all his plans were good, they were imperfectly executed, and have proved perplexing and useless. His principal publications in this department were: 1. “Bibliographia Juridica et Politica,” Amsterdam, 1680, 12mo. 2. “Bibliotheca medica et physica,” 1691, igmo, enlarged in 1696. 3. “Gallia critica et experimentalis ab anno 1665 usque ad 1681,” Amst. 1683, 12mo. This is a useful index to the articles in the “Journal des Savans.” 4. “Bibliographia mathematica et artificiosa,” 1685, improved and enlarged, 1688, 12mo. 5. “Bibliographia historica, chronologica, et geographica,” 1685, 12mo, and continued in four parts until 1710. 6. “Bibliographia | crudilorum critico-curiosa, seu apparatus ad historian! literariam,” Amst. 1689—1701, 5 vols. 12mo, a sort of general index to all the literary journals, but containing too many alphabets to be easily consulted. It extends from 1665 to 1700. 7. “Incunabula typographic, sive Catalogus librorum proximis ab iwentione typographic annis ad annum 1500, editorum,” Amst. 1688, 12mo, jejune, says our English bibliographer, and erroneous. Indeed each of these undertakings, to be completely useful, would have required more years than Beughem bestowed upon the whole. ¹
