The pope of literary self-reference is Éric Angelini, whom you will find on the In brief page and in the article Playing with numbers. His website—as comprehensive as it could possibly be, and suitably self-referential (cetteadressecomportecinquantesignes.com)—is essential viewing. Among its many gems are all the words whose letters, in Scrabble, spell out their total point value (the subscript 0 denotes blank tiles used as wildcards).
Staying with word games, in 2006 Frédéric Martin devised a "self-referential 69 × 69 square" that will appeal to crossword and Scrabble enthusiasts. With a total of 10,248 both horizontally and vertically, the original French square contains the French word for "zero" 0 times, the French word for "one" 1 time, the French word for "two" 2 times, the French word for "three" 3 times, the French word for "four" 4 times, the French word for "five" 5 times… and the French word for "hundred" 100 times! This extraordinary grid is, of course, catalogued on Éric Angelini's website. On his Web log "Journal d’un Terrien", Serge Boisse also offers a section on "Self-descriptive sentences" for fellow enthusiasts.
