This is a personal (and partial) list, arranged only alphabetically. It is no accident that many of these titles hail from the 1970s: it was a period of astrological renaissance; and not at all coincidentally I began learning astrology at that time. There are many other fine tomes out there; but these have been and continue to be MY inspiration.
