I am happy to share online this freely downloadable PDF of The Handbook of the Bombay Archives (B.G. Kunte, ed., compiled by Sanjiv Desai and R.S. Pednekar, Mumbai: Government of Maharashtra Department of Archives, 1978).
Long out of print and unavailable, this is an essential guide to the Maharashtra State Archives, one of India’s richest and best managed repositories of historical documents, located at Elphinstone College in Kala Ghoda. Enjoy and share widely!
