Books about 'The Shining'

[Raq]

Hi,
I'm writing a work on the Shining for my B.A. at college and I was wondering what books should I read. My topic is 'the portait of insanity in S.King's 'The Shining' ', and of course I have to have some books to relate to in my reserch, it can't be my own interpretation. In other words , I have to have something already published to confirm (or discard) my theories and interpretations.
So anyway, do you guys know of any books that take on the subject? Or at least mention the book? If they are available in the US or UK only, that's fine cause my friend lives there and he can send me those (as I mentioned in an other topic I'm from Poland).
Those could be even articles in a newspaper etc. Something that speaks of The Shining.
I would be more than thankful for your help

Here are a couple to get you started:

The Art of Darkness by Douglas E. Winter
The Stephen King Universe by Wiater, Golden & Wagner

There's also The Shining Reader (Starmont Studies in Literary Criticism), updated as Discovering Stephen King's "The Shining" (Starmont Reader's Guide) by Tony Magistrale from Borgo Press.
