Books

I personally own and enjoy all the books on this list and can recommend them. If you’re looking for books on your state that are not listed here you can likely find them by searching some of the series mentioned here.

Some of these books are older, out of print, and can be hard to find. I have included ISBN numbers when available to help you locate them in libraries and on eBay.

Even old and out of date books can have forgotten about gems of information in them.

I have included as many links as I can to the books on Amazon because I earn a small commission from qualifying purchases made after clicking one of my links, even if you ultimately choose another product. This costs you nothing, but the small commissions earned on referrals supports the ongoing creation of content on this site. Thank you for your support.

Rockhounding:
I love having rockhounding guide books in my personal library but they become outdated rather quickly sometimes. Areas that were once accessible can become off limits at anytime. It’s up to the individual to confirm an area is accessible.
