Islamic Peoples Of The Soviet Union [PDF ebook] 

First published in 1987. The aim of this historical and statistical handbook is to answer three basic questions about the Islamic peoples of the USSR: who they are, where they are and how many of them there are. It is convenient to speak of them as ‘Soviet Muslims’, grouping them all together under a single, collective heading, but they are in fact quite disparate. For this reason it was decided to treat each ethnic group individually here.
