I gave it 5 stars because it deserves the flowers. I do wish the paper was a little better quality. I think it would help make the pictures pop more. Regardless, this book is worth every penny. I haven't found anything else like it. The book is clear, concise, and isn't bogged down with too many details - just the facts m'am. It's a perfect starting reference to send someone down 101 different rabbit holes. I hope someday he puts out a hardback version on thick, slick paper with beautiful, glossy photographs. That would be lovely. For now, this will more than suffice. You get just enough about each artifact to get you going. From there, you can decide how to use your favorite search engine.
