Hi Friends, I have heard that this book, The Colas by Neelakanta Sastri, is not a easy one to find. The book was published by publication division of University of Madras. Recently I got this book from a publisher from New Delhi, costing Rs 850. I am not sure whether the book is sold via University itself. However it seems that the printed price of the book is Rs 250 only. If anyone is interested to buy this book, they can contact the publisher, contact details are there in their website. The book is not listed in the website hence call and order.
If this book is indeed easily available form University of Madras bookshop then I think I paid some extra amount to procure this. Anyway, if you are interested then there is a place from where you can get this.
