| | CATHOLIC ENCYCLOPEDIA: Index of Prohibited Books |
 | | Index of Prohibited Books, or simply "Index", is used in a restricted sense to signify the exact list or catalogue of books, the reading of which was once forbidden to Catholics by the highest ecclesiastical authority. |
 | | Roman "Index of Prohibited Books" (Index librorum prohibitorum), published in 1559 under Paul IV, was very severe, and was therefore mitigated under that pontiff by decree of the Holy Office of 14 June of the same year. |
 | | Concerning the curious indexes of 1590 and 1593, which were printed but never promulgated see Hilgers, "Der Index der verbotenen Bücher", 12 sq., 524 sqq., 529 sqq. |
