The journal Russian Literature Vol. 106 (May-June 2019) is a special issue on the Russian Gothic, including under the Soviets and after. Appears to be all in English, but is paywalled Elsevier stuff. Judging by the abstracts, it’ll help a lot if you’re conversant with the latest strands and currents of political thinking inside Russia — to know what they’re talking about when they refer to things like “the neo-Eurasian dream of a New Russian Middle Ages” etc.

A previous special issue was on Magic, Magicians and Russian Literature (Oct–Nov 2017) but there about half the essays appear to be in Russian.
