The "Introduction to Altaic Linguistics" is designed as a manual for university students. The first part gives a survey of the Altaic languages, i.e., Mongolian, Manchu-Tungus, Chuvash-Turkic and Korean, and a classification of the Altaic languages and classifications of languages within each family. The second part presents a brief outline of the history of studying Altaic linguistics. It also contains a number of bibliographical data and bibliographies of famous scholars. The third part gives a brief history of the Altaic theory. The subsequent portions of the book deal with problems of mutual influences of the Altaic languages (e.g., the Turkic influence of Mongolian), Altaic influences in non-Altaic languages (e.g., the Turkic influence on Sayan-Samoyed, or Mari), non-Altaic influences in Altaic languages (e.g. Sogdian elements in Turkic), and structural features common to all Altaic languages.
