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.
