This book is a great (maybe the best) source for those who are interested in Russian cars built until 1917. Nearly all manufacturers and coachbuilders are featured on 88 pages with many archive photographs. Although language is Russian only. Published in 2007, I don't know whether it is still available anywhere.
Among the attached pictures you can see a summary, where you can notice the number of featured makes of manufacturers and coachbuilders.
Almost forgot to mention that the second edition is planned as far as I'm aware, which will include some new material.
