This series of fifteen paperback volumes offers verbatim extracts from the Edgar Cayce Readings on a range of specific topics. It can be considered as an updated and much smaller version of the now out-of-print 24 hardcover volume series known as the Edgar Cayce Library Series.
One word of warning is in order though: these books contain just quotes from the readings related to the title of each book, with no additional comments, just as the Edgar Cayce Library Series volume did.
