I'm looking for a forum of rare books, to get info about some rare books I have?

Answer 1

There is a site online that is basically a conglomerant of hundreds of small to mid-range bookstores. I have used it before to get a general idea of what rare books are worth because the have an enormous selection and you can narrow your search by fisrt-addition, etc.

I know it is not a forum but it may help:
