Those are both great Welles sites, Gregory. The Unseen Welles page especially is a terrific contribution. It sure would be great to track down some of those unfilmed and unpublished screenplays. In a sense, they ARE Welles movies, that just happen to exist on paper instead of film.
As for the archives, I was amazed at how many Welles books you listed. Do you own all those? Many of those mag and newpaper articles I have already, but some I've never even heard of, like the black actress who claims she smoked weed with Welles (of course, Welles later told Bogdanovich that marijuana didn't do anything for you except give you incredibly bad breath, so obviously he didn't get high on it -how then, to explain the hallucinatory quality of his films?). That article would be fun to read, as would the one about Welles burning down Cybill Shepard's house.
