From Wikipedia, the free encyclopedia
The Index Librorum Prohibitorum (English: List of Prohibited Books) was a list of publications prohibited by the Catholic Church. A first version (thePauline Index) was promulgated by Pope Paul IV in 1559, and a revised and somewhat relaxed form (the Tridentine Index) was authorized at the Council of Trent. The promulgation of the Index marked the "turning-point in the freedom of enquiry" in the Catholic world.
A complete list of the authors and writings present in the successive editions of the Index is given in J. Martínez de Bujanda, Index Librorum Prohibitorum, 1600-1966. A list of the books that were on the Index is given also on the "Beacon for Freedom of Expression" website
