...I write slowly. Therefore, I am Joseph Heller.
Vanity Fair has an excellent article on the publication history of Catch-22, a book that is on my all-time favorites list. (Catch-22 the movie also has the distinction of being the only place I can stomach Art Garfunkle's acting).
How different would the novel have been as Catch-18?
