Are you looking for information about only the what is currently Russia, because there's a tonne of stuff written on the Ukrainian Makhno.

This is actually a topic I'd like to read more on too. I googled a bit but the only additional book I could find was Victor Serge's memoirs of a revolutionary. Serge started out as an anarchist.

I'll try to find more books in the coming days.

It looks like disappointingly little has been written.

I did find this page with an impressively detailed time line. A couple of books are mentioned at the bottom.

I came across the names of a few articles, but didn't search for the articles themselves. If you find some online please let me know.
