The science fiction and fantasy section of paperbacks and hardcovers has some good representation of modern and older titles. The paperbound titles are usually around $3 to $6 each.
Those looking for vintage, postwar crime / detective / mystery paperbacks will find a good selection available. These are comparatively higher priced, from $10 on up.
And if you're into New Age books, they have you covered:
There horror section inevitably oversubscribes to Stephen King and Dean Koontz, but there are some Paperbacks from Hell nestled there on the shelf.
Higher-end antiquarian / vintage paperback books are housed in the back of the store. There is an impressive shelving system for these paperbacks, in fact, the most impressive such shelving system I've yet seen in a bookstore. Needless to say, these vintage paperbacks are in 'very good' to 'like new' condition, and have prices of $10 on up.
Old Editions is the sort of place where you easily can spend several hours poking among the shelves and looking for offbeat treasures. I came away with a nice collection for myself:
If you find yourself in the greater Buffalo area and you have a couple of hours of free time, it's well worth making a detour to Old Editions.
