The third version was translated into Greek and submitted in 34 books between 1977 and 1983 from Akadimos publishing company (owned by Giannis Giannikos), which has also translated various Soviet encyclopedias and literature. All articles that were related to Greece or Greek history, culture and society were expanded and hundreds of new ones were written especially for the Greek version. The encyclopedia contains, for example, both the Russian entry on Greece as well as a much larger one prepared by Greek contributors. Each article written especially in the Greek version is marked with the note "Greek version supplement" (or "Συμπλήρωμα ελληνικής έκδοσης" as written in the Greek translation).
