Art Archive Resources for Artists? Books?

EDIT - I just spotted the "Official Reference Material Thread." I would've posted this there first, but I didn't see it, and I don't see a way of deleting this post...

I was unsure where to place this post; this forum seemed the most logical choice.

I'm already looking around amazon.com for this, but I thought some of you may have some suggestions off the top of your head.

(Please note: I'm interested in printed material, not web sites.)

I do have some old Star Wars picture books and collector's magazines from when I was a kid, but I think they're in storage (unfortunately).

I was wondering if someone could please provide me with the titles (and author names) of books that have some large (at least 8 x 10 inches or so), clear photographs from the Star Wars films (I'm especially partial to the original triology, Ep. 4, 5, 6).

I'd like at least one book with a good selection of quality photographs so that I may use them as guides for drawings and maybe some paintings.

I'm sure there's probably one really great one out there somewhere, but I bet it costs a small fortune -

- on top of recommending that one, whatever it may be, if you could also please provide me with other titles that are less expensive, I'd appreciate it! Thank you.
