Jack London's writing was censored in several European dictatorships in the 1920s and 1930s. In 1929, Italy banned all cheap editions of his Call of the Wild
Thomas Paine, best known for his writings supporting American independence, was indicted for treason in England in 1792 for his work The Rights of Man, defending the French Revolution
Jean-Jacques Rousseau's autobiography Confessions was banned by U.S. Customs in 1929 as injurious to public morality. His philosophical works were also banned in the USSR in 1935, and some were placed on the Catholic Church's Index of Prohibited Books in the 18th century. (The Index was a primarily a matter of church law, but in some areas before the mid-19th century, it also had the force of secular law. A summary of the contents of the last edition, published in 1949, is available from the Internet Archive. The Index was finally abolished in 1966.)
Leaves of Grass, Walt Whitman's famous collection of poetry, was withdrawn in Boston in 1881, after the District Attorney threatened criminal prosecution for the use of explicit language in some poems. The work was later published in Philadelphia.
Title: Fanny Hill
Author: Cleland, John, 1709-1789
John Cleland's Fanny Hill (also known as Memoirs of a Woman of Pleasure) has been frequently suppressed since its initial publication in 1749. This story of a prostitute is known both for its frank sexual descriptions and its parodies of contemporary literature, such as Daniel Defoe's Moll Flanders. The U.S Supreme Court finally cleared it from obscenity charges in 1966.
Title: Ulysses
Author: Joyce, James, 1882-1941
Ulysses by James Joyce was selected by the Modern Library as the best novel of the 20th century, and has received wide praise from other literature scholars, including those who have defended online censorship. (Carnegie Mellon English professor and vice-provost Erwin Steinberg, who praised the book in 1994, also defended CMU's declaration that year to delete alt.sex and some 80 other newsgroups, claiming they were legally obligated to do so.) Ulysses was barred from the United States as obscene for 15 years, and was seized by U.S Postal Authorities in 1918 and 1930. The lifting of the ban in 1933 came only after advocates fought for the right to publish the book.
