No astrologer's library can be complete without the ephemeris with the latest data from NASA's Jet Propulsion Laboratory. The American Ephemeris by ACS is the most accurate ephemeris in the world today. In addition to planetary positions for every day from 2000 through 2050, it includes a wealth of data - solar and lunar eclipses, aspectarian of Jupiter though Pluto, Chiron, Synetic Vernal Point, Moon phases and more.

A Must For Any Astrologer, July 10, 2003

I have two (2) expensive astrology computer programs and still rely on The American Ephemeris for daily information. No astrologer, novice or professional, should be without it. I handicap sports utilizing astrology and it has been of tremendous help to me. The only drawback I can find is it only lists Chiron's positions on a monthly basis and not on a daily basis. Outside of that I feel the book is a "must have" for the astrology library.
