Title: Don't Waste Your Money
Product review: I purchased my copy used (20$) and (after my initial delight at the bargain) was disappointed. I had hoped for a more technical intermediate-level expansion of Wheeler's intriguing but vague "Journey into Gravity and Spacetime." This book is instead largely a hodge-podge of specialty articles of interest only to advanced professionals in the field. Unless you have money to burn, invest it in another text, like "Gravitation," by Thorne, Wheeler, etc., which isn't great but is useful.
