The books in this section are usually hardcover and in decent condition, though we'll sometimes offer hard-to-find books in lesser condition at a reduced price. Though we often put images of the book with their original dust jackets, the copies here won't always (or even often) have them. If that is important to you, please call ahead or say so in the order comments!
In 1930, as a young man, Clyde Tombaugh made headlines:
NINTH PLANET DISCOVERED ON EDGE OF SOLAR SYSTEM
He had discovered Pluto, the planet farthest from the sun.
This is the story of his tireless search for Planet X–a story of challenge, suspense, and triumph!
