I'll check more. Most part of new published books about WWI are translated from foreign authors. In soviet times this war was unpopular and shoun as forerunner of revolution only.
About Civil war - the best for my opinion: N.Kakurin. - How the Revolution was combat.
And now some memoirs was published - Denikin, and different digests. You can check site www.posev.ru - they issued some books & magazines about Civil war. But everything in Russian.
