Interesting tidbit: Jonathan Coe's 2001 novel, The Rotter's Club, closes with a single 33-page sentence consisting of 13,995 words - the longest ever written in the English language. What a doozy!
There are many other examples of "restricted writing":
Gadsby is an English-language novel of 50,100 words, none of which contain the letter "e."
Never Again is a novel by Doug Nufer in which no word is used more than once.
Lots more...
