Mini books

[alendark]

Anyone know where I can get some small size books (no more then 5 inches on a side). Topics can be varied but I would ideally prefer things like astrology, the occult, paranormal, magic, mysticism, ghosts, folk lore/folk tales, etc etc.

I need roughly 30-50 different books and I would prefer not to spend a fortune on them.

Any help would be greatly appreciated.
