The first installment: provides all available biblio. info. concerning works in Jyotihsastra & related fields & bio. info. concerning their authors. Jyotihsastra is traditionally divided into 3 skandhas or branches: hora or genethlialogy and other forms of horoscopic astrology, ganita or mathematics & mathematical astronomy, and samhita or divination. The related fields to which attention is paid in this study are cosmology & geography (largely of the Jainas) and those aspects of dharmasastra that involve the determination of the proper times for the performance of ritual acts. This vol. contains in their initial form the list of abbrev. of journals & series, the biblio., the list of mss. catalogues, and the articles concerning authors whose names begin with a, i, u, r, l, e ai, o, and au.
