A BOOK ON SHANKARA’S DATE

When searching the net for a digital / hard copy of the “Shankara’s Date” book (published in the year 1981) which was required by one of my students,   I chanced to visit this following link where one K.Parthasarathy has typeset and uploaded this book; the front page says it is a revised, unpublished version (1983). The book is downloadable in PDF format in A4 size.
