Yes, there used to be a magazine called Misha. I am also searching for it, from quite some time but not have been able to get any. Neither I know of people who have this magazine. These books stopped publishing after the former USSR collapsed. As of now, most of these books, baring a few exceptions republished by CBS in India are out of print. And as of now I have not posted any links to soft-copies of these books here. But many of them are available on the internet already.
