Notes: • Worldcat states 158 pages. • "First edition published March 1973" on copyright page in richarddalbyslibrary.com photo; however, the book is copyrighted 1974 by Pyramid Communciations, Inc., so the copyright year seems to be a mistake (as is the publisher's name, which should be Communications, and is spelled correctly twice further down the copyright page). The LCCN on the copyright page, 73-21124, isn't on the LOC website.
