Memoirs of Fanny Hill

Often with banned books the publication story is as interesting as the book itself, and Memoirs of a Woman of Pleasure, or Fanny Hill as it became known, is no exception. It was penned by John Cleland in 1748 while he was in debtor's prison in London. Considered "the first original English prose pornography," Fanny Hill was denounced for "corrupting the King's subjects," and once it was outlawed, it became a widely pirated book. This act would lead the trend that there's nothing better for sales than to get banned.
The story is written as a series of letters from the young Fanny Hill, who loses her parents at the age of 15 and is pushed into a life of lasciviousness. The actual contents of Fanny Hill might seem tame by today's standards, but what sets it apart is its delightful prose and well-wrought story line.
The bawdy novel Fanny Hill (1748), written by John Cleland as an exercise in what he imagined a prostitute's memoirs might sound like, was no doubt familiar to the Founding Fathers; we know that Benjamin Franklin, who himself wrote some fairly risque material, had a copy. But later generations were less latitudinarian.

The book holds the record for being banned longer than any other literary work in the United States--prohibited in 1821, and not legally published until the U.S. Supreme Court overturned the ban in Memoirs v. Massachusetts (1966). Of course, once it was legal it lost much of its appeal; by 1966 standards, nothing written in 1748 was liable to shock anybody. “Civil Liberties:About.com”
