don't know of any books, but there are some articles / web links in the library. When I have a blank that I can't identify, it is FIS wood. (Found In Shop) :biggrin:
It really depends on how in-depth you want to get. If you get into looking into cell alignment to help determine species, there are books on that or there are landscape books that can be helpful as well (and everything in between). My best recommendation is to join the International Wood Collectors Society (www.woodcollectors.org) and you'll find a lot of different possibilities from there. Bob I.
