Query: Good representative book on Forest Green Glass

As a casual collector of Anchor Hocking forest green glass over 30 years, this was my first ever book I'd ever gotten (or seen) dedicated to my favorite type of glass. I was thrilled to see that nearly everything I had was represented and it gave me better background about the items. I used it that very weekend to recognize a small green vase I would otherwise have not known was anchor hocking (had gold paint on it). But don't use the prices as indications of the real value of the items, unless maybe yours are new-never-used still in original boxes. you couldn't sell your collection fo the prices listed I don't believe -- I'm still picking them up for just a few dollars at "junk" stores,and yard sales. And ebay items are never over $10.
