In 1985 COMECON countries published more than
64 thousand documents indexed in the US-produced Web of Science database, of
which only 1-2% were coauthored with American scientists. USSR alone accounted
for almost 40 thousand publications, or 4,4% of the total world output, not
counting numerous quality Soviet journals missing from the Web of Science. By
2013 Russia ’s share was only
1,6% and all former partner communist states switched to EU or USA as
their main collaborators. This article aims to provide a brief statistical
overview of these massive changes by combining bibliometric data with some
general development indicators and historical remarks.
