We studied the population of articles on higher education published in academic journals by researchers from post-Soviet countries in the last three decades. We found that post-Soviet countries contribute differently to the overall publication output, with only Russia, Lithuania, and Estonia having more than 100 articles in journals indexed in Scopus. Countries also have different publication profiles in terms of articles' language, topics, methodology, and the balance between articles in local and international journals. In comparison with a sample of international articles, post-Soviet authors publish a substantially smaller share of research articles, and articles about teaching and learning issues, student experience and outcomes, and academic work, but a larger share of policy-related articles and articles about system policy and history. Researchers from one post-Soviet country collaborate much less within their country compared with authors from the international sample, where people collaborate more actively between institutions within a country. At the same time, scholars from different post-Soviet countries do not collaborate with each other. Our analysis demonstrates the disunity of the community of post-Soviet scholars disconnected by national borders.
