[quote:47c7b65430="wcaptain"]Gary is right. Field guides and reference book (Krys' one and the thick "Birds of India subcontinent) are available at big book stores around Delhi. Can't remember which area in Delhi. It is roughly around Park Hotel, where there are a lot of airline offices.
Probably no book shop is around National Parks in India. Try you luck.

If there are no birds books store selling around the National Park, then it will be a problem because I will go Delhi from Agra and stop at National Park in the mid-way. Which means I can't buy a book at Delhi before I visit the National Park. Or I hope I can find a book store where selling birds book in Kolkata since Kolkata will be the first stop of my India trip. Anyway, thanks for your kindly help, Captain.
