# List of authors and works on the Index Librorum Prohibitorum

This is a selected list of authors and works listed on the Index Librorum Prohibitorum. The Index was discontinued on June 14, 1966 by Pope Paul VI.
A complete list of the authors and writings present in the subsequent editions of the index are listed in J. Martinez de Bujanda, Index Librorum Prohibitorum, 1600–1966, Geneva, 2002.
The Index includes entries for single or multiple works by an author, all works by an author in a given genre or dealing with a given topic. The scope of the prohibition is defined by a Latin phrase in the Index:
* Omnia opera dramatica: all plays
* Omnes fabulae amatoriae: all novels, or romances
* Opera omnia theologica: all theological works
* Opera omnia: all works (see note below)
The Index includes entries banning all works of a particular writer. Most of these were inserted in the Index at a time when the Index itself stated that the prohibition of someone's "opera omnia" (all his works) did not cover works whose contents did not concern religion and were not forbidden by the general rules of the Index, but this explanation was omitted in the 1929 edition, an omission that was officially interpreted in 1940 as meaning that thenceforth "opera omnia" covered all the author's works without exception.

## Reversals and non-inclusions

There have been cases of reversal with respect to works that were on the Index, such as those of Nicolaus Copernicus and Galileo Galilei. The Inquisition's ban on reprinting Galileo's works was lifted in 1718 when permission was granted to publish an edition of his works (excluding the condemned Dialogue) in Florence. In 1741 Pope Benedict XIV authorised the publication of an edition of Galileo's complete scientific works which included a mildly censored version of the Dialogue. In 1758 the general prohibition against works advocating heliocentrism was removed from the Index of prohibited books, although the specific ban on uncensored versions of the Dialogue and Copernicus's De Revolutionibus remained. All traces of official opposition to heliocentrism by the church disappeared in 1835 when these works were finally dropped from the Index.
Not on the Index were Aristophanes, Juvenal, John Cleland, James Joyce and D. H. Lawrence. According to Wallace et al., this was because the primary criterion for banning the work was anticlericalism, blasphemy and heresy.
Some authors whose views are generally unacceptable to the Church (e.g. Karl Marx) were never put on the Index; nor was Charles Darwin (see Evolution and the Roman Catholic Church).
Works that were included in the Index, and later removed, include:
| When banned | Author | Works |
| 1585 to 1881 | Dante Alighieri | De Monarchia (1312–13?) |
| 1616 to 1835 | Nicolaus Copernicus | De revolutionibus orbium coelestium (1543) |
| To 1835 | Johannes Kepler | Astronomia nova (1609); Harmonices Mundi (1619); Epitome Astronomiae Copernicanae (1617–21) |
| | Sade | Justine (1791); Juliette (1797–1801) |
| | Madame de Staël | Corinne ou l'Italie (1807) |
| Until 1959 | Victor Hugo | Notre Dame de Paris (1831); Les Misérables (1862) |
