I have a set (not a full set, a few books are missing) of Illustrated Library of Nature. These are great for kids to do book reports or just to learn about nature. I have volumes 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, and 16. They are in good condition except volume 5 has some major damage to the top spine, looks like a dog chewed on it or something. I would like 6 credits for the whole set. PM me if you are interested.
