Of the books that I have on them, the most informative is The Three Stooges Scrapbook by Jeff Lenburg, Greg Lenburg, and Joan Howard Maurer (Moe's daughter). It not only has stills from their films, but also photos of all kinds of Stooges memorabilia, they even have the shooting dates for each 2 reeler and feature they appeared in, and little facts and anecdotes about each one as well.
