The following is from the NASA website:
The book "Getting a Feel for Lunar Craters" was created with the NLSI (NASA's Lunar Science Institute) and features tactile diagrams of the lunar surface designed to educate the blind and visually impaired about the wonders of Earth's moon. David Hurd, a space science professor at Edinboro University of Pennsylvania, Edinboro, PA., is the book's author. He and tactile engineer John Matelock began creating tactile astronomy tools after a student with visual impairment signed up for Hurd's introductory astronomy course.
The tactile graphics in this book are quite good.
It is currently in the process of being reprinted and not available.
