I think there are books out for each state and those could be interesting. I'd been wanting to ask a neighbor what kind of a tree he had in his yard and last summer I finally caught him. He told me it was a black gum then produced a book of trees in MI. Sure enough, black gum it is and I had no idea we had any of those in this state.
Parental units got me that for Christmas 1981,its still pretty good shape though the paper dust sleeve is long gone.
It's all firewood isn't it? That whole book can be put into one page under the classification of firewood!
