Research note
The Index Librorum Prohibitorum was the Roman Catholic Church's list of books it told Catholics not to read or publish. It began in the sixteenth century and was discontinued on June 14, 1966, by Pope Paul VI.
This page is a research note for the Books of Titans reading project. It sets a selected public list of Index authors and works next to the authors, library timeline, and reading log already on this site. It is history for a Great Books project. It is not an endorsement of censorship, and it is not a verdict on any book or writer.
The rows come from the English Wikipedia article List of authors and works on the Index Librorum Prohibitorum, retrieved October 6, 2026. Wikipedia calls that article a selected list of the final 1948 edition, with later additions up to 1966, plus some works that were later removed. It is not the complete Index. For the full record, Wikipedia points to J. Martínez de Bujanda, Index Librorum Prohibitorum, 1600-1966 (Geneva, 2002). Nothing below was added from outside that Wikipedia page.
Wikipedia also says Charles Darwin and Karl Marx were never placed on the Index, and that Aristophanes and James Joyce were not on it. Charles Darwin, Karl Marx, Aristophanes, and James Joyce are on the Books of Titans author list. Galileo Galilei is one of the authors here too. Wikipedia discusses his case among reversals and does not give him a row in the tables this page uses.
