Just found a number of references to books on Goa at the "Indian Amazon.com" aka FirstandSecond.com. Check it out!

PS: Would you believe there are seven books with the title of just Goa or Goa! ? They are by travel-guide author David Abram, journalist and author Mario Cabral e Sa, Harper Collins, (Sir) JM Richards, former Governor Romesh Bhandari, Rupa & Company, and (I think, the did-you-know-it trivia master) V Chandra Mowli.
