Actually, I thought I'd post this bookstore that I went to today. It's located in Tulsa (OK). I was in there like 5 hours (only left b/c they were closing and still dragging my feet LOL).
They had so many books in there and many are out of print and very old books on SO many topics I can't really begin to name them all. I bought mainly books on astrology and numerology, but they were some of those good old ones from early 1900's-1960's--a couple 80's books. Some of the books were very reasonably priced as well (the ones I purchased ranged from $4-15).
Anyway, if you are ever looking for out of print/date books, maybe give them a call so they can check their inventory if you can't find them in your area, as I was told they do mail order as well. They have some stuff listed on their website, but not everything they carry. For instance, I just looked up the dream section online and they only have 1 book listed, but had a nice sized section just on dream books.
