The Overlook Hotel is simply the best site about The Shining on the internet. There are dozens of never before seen photos from the making of the film (including how Nicholson was propped up frozen in the snow at the end), new posters, artwork, tattoos, copies of screenplays, anything you can think of. Lee Unkrich is the caretaker of the site and I salute him.
Just in case you need more ephemera on The Shining here is that little article On Newfound Footage.
