I have myself just achieved a first input (including pada-paa.tha and variant readings of the various editions - I have still to check one before to propose the text on GRETIL - here attached the work as already done) + French translation (a simple new Sanskrit commentary is also planned because I am not always satisfied by the existing ones).
Two noteworthy studies on the work are:
- Ferdinando Belloni-Filippi, "Il Poema Demoniaco (raak.sasakaavyam)", Giornale della società america asiatica italiana 19, 1906, pp. 83-102
