Trekking and Climbing in the Indian Himalaya
Although out of print, you can still find it used as well as new in some book shops in India. In addition to treks, Trekking and Climbing in the Indian Himalaya, covers many trekking peaks as well as a couple more technical ones. I used this book as an outline when I climbed Chamser Kangri in Ladakh. The practical information is pretty brief on the treks and climbs themselves and there is a lot of extra nonessential information and pictures that makes it pretty heavy to trek with, but the book covers some interesting routes and peak not covered elsewhere. If you can get your hands on a copy it worth a browse to get some ideas.
