During his lifetime, Kozminsky wrote several books on astrology and numerology- the scientific and practical application of numbers. Zodiacal Symbology and It's Planetary Power, Book One in which the Planetary Influence for Each Degree of the Zodiac accompanies the symbol for the first time. Book One includes a comprehensive coverage of the signs Aries through Virgo. Book Two covers Libra through Pisces.

"After some years of careful study in the endeavour to fix the special planetary influence attached to each degree of the Zodiac, I am now enabled to present it to many sincere students who find in astrology a safe and sure foundation upon which the approaching true civilization will demand." -- Dr Isidore Kozminsky
