Pulitzer-winning fanfic: a non-exhaustive list

A non-exhaustive list of books that would be considered fanfic except for the fact that they won the Pulitzer Prize (provided as a service to writers who believe that fanfic is "immoral, illegal, plagiarism, cheating, for people who are too stupid/lazy/unimaginative to write stories of their own" and who feel "personally traumatized by the idea that someone else could look at your characters and decide that you did it wrong and they need to fix it/add original characters to your universe/send your characters to the moon/Japan/their hometown.")

* Jane Smiley's novel A Thousand Acres, a modernized AU (Alternate Universe) retelling of King Lear and winner of the 1992 Pulitzer Prize for Literature. King Lear is itself a hybrid of multiple folk and fairy tales

* Rodgers & Hammerstein's Tony-Award-winning South Pacific, which was based on James Michener's Tales of the South Pacific and is the only musical to win the Pulitzer Prize that is based on *another* work that also won a Pulitzer.

* Geraldine Brooks' March, a parallel retelling of Little Women and winner of the 2006 Pulitzer Prize for literature

* Stephen Sondheim's Sunday In the Park with George, which is half-original fic, half-RPF (real person fiction) based on the artist Georges Seurat, and winner of the 1984 Pulitzer Prize for Drama

* Jonathan Larsen's Rent, which is an AU fanfic of La Boheme (much like the movie Moulin Rouge, an AU hybrid crossover fanfic of La Boheme and La Traviata) and winner of the 1996 Pulitzer Prize for Drama

* John Corigliano, 2001 Pulitzer-Prize winner for Music, who wrote the opera Ghosts of Versailles, a postmodern fantasy RPF/fanfic crossover AU about Pierre Beaumarchais and the characters from his play La Mère coupable.. Those characters were previously fanficced twice over, in two separate operatic masterpieces: Rossini's The Barber of Seville and Mozart's Marriage of Figaro, both based on the other 2 Figaro plays by Beaumarchais.
