I picked up this and a couple of other volumes from Time-Life's Mysteries of the Unknown series at a used bookstore in Chicago somewhere and brought them with me to California to give to my host, Mike Miley, while I was visiting him in Sonoma. Like most Time-Life books, the principal concern seems to have been marketing. The coverage of the Rosicrucians, Masons, Golden Dawn etc. is shallow, but the pictures, when not stupid, are pretty enough.
