Note 1306 — Chapter IV · CENSORSHIP.
Reading edition
Catalani de Secretario Congr. Indicis, p. 31 (Rome, 1651).
The only attempt made to compile a Roman Index Expurgatorius was in 1607, by Gianmaria Guanzelli da Brisighella, Master of the Sacred Palace. It never advanced beyond the first volume and was suppressed in 1611. That volume consists of 599 double-columned 12mo pages and only contains fifty-two authors, so numerous are the expurgations, many of them as trivial as those of the Spanish censors.
