We live in a wonderful time with all the information and misinformation in the world right at our fingertips. That’s all well and good, but a lot of times I still prefer to have something more tangible, as in a physical book I can hold. A coworker brought in one of these to show me and I was very impressed with the depth of information, the illustrations, and how everything was compiled. I liked it so much that I ended up buying my own (used, good condition, $7 plus $5 for shipping) If you’re a tree nerd like me and come across this guide for cheap, I highly recommend scooping it up.
