The book includes unpublished or little-known works of the outstanding Soviet scientist E.V. Tarle. The breadth of scientific horizons and the mastery of historical storytelling were fully manifested in the essay "The Babef Case," articles and reviews on Russian and world history. Most reviews were published anonymously or under a pseudonym. Of considerable interest is the lecture course on the philosophy of history, read by E.V. Tarle in 1908. The final sections contain letters from E.V. Tarle, as well as memories of him.
