I am trying to find/order a copy of Vishva Bandhu's Brāhmaṇoddhārakośa, which was published in 1966 by the Vishveshvaranand Vedic Research Institute and is listed in the catalog that one can download here on the VVRI's website: http://vvrinstitute.com/about.html. 

Although mention is made on the same website of a Book Agency and Sales Department, I haven't been able to figure out how to place an order, nor have I received responses to my emails to the following contact addresses: info@vvrinstitute.com, vvrinstitute@gmail.com, vvr_institute@yahoo.co.in.

Any help would be much appreciated. 

Best wishes, 

Dieter Gunkel
