Index Librorum Prohibitorum
The developments since the abolition of the Index show "the loss of relevance of the Index in the 21st century". 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 can be found on the World Wide Web.
