Throughout the astrology community there is increasing awareness of the importance of referencing our sources for material so others may reliably and intelligently build upon or challenge our assumptions. Now organizations and schools are encouraging more professionalism in preparation for lectures, workshops books and articles. Availing ourselves of appropriate historical and academic support to reference our astrological presentations will go far toward the enhanced professionalism and respect for our discipline to which we all aspire. Since the 1980’s, through the work of Lois Rodden, we have learned to document the sources and quality of our birth data. Now we must give equal diligence to providing full background information and references for our lectures and published works. The Marion D. March Electronic Library serves that need well.
