This book is intended to facilitate access to the amazing wealth of documents written in the five major South Indian scripts. It focusses on the South Indian Sanskrit tradition, but also takes into account the modern alphabets of the respective Dravidian languages. The sometimes bewildering variety of the five scripts is mapped out in altogether c. 5200 basic characters, ligatures (i.e., vocalizations), conjuncts/consonant clusters, numerals, abbreviations etc. Special care has been taken to break down the complexity of Grantha Tamil in a system of graphic classification. The material surveyed comprises Sanskrit manuscripts as well as the Southern tradition of Sanskrit printing, and books in Dravidian languages (including Tranquebar prints).
