The monthly journal Pod Znamenem Marksizma (PZM) began in 1922. There is a translation of the titles of the first 8 volumes of PZM at https://libcom.org/library/under-banner-marxism
I admit that I myself only translated some articles after much encouragement from others, so I understand people's reluctance to seriously look into and discuss PZM. What titles are particularly interesting? Are the subjects in general interesting? Or is it just the average of what one expects of any Marxist journal? Are there any particular questions?
