Via Russian History Blog, I learn of the appearance of Фронтирных исследований/Journal of Frontier Studies:
Just this week a new online journal for Russian Studies arrived, The Journal of Frontier Studies/Zhurnal frontirnykh issledovanii. It is being edited by a group of scholars at Astrakhan State University, and aspires to put Russian and Western scholars into conversation. They are planning on publishing articles in English down the line.
I haven’t had time to investigate it yet, but it certainly sounds promising.
