The collection of articles and materials, Gottfried Kratz: Man, Scholar, Colleague, Friend (Moscow, 2025), was prepared by the Turgenev Society in Moscow with the support of the I.S. Turgenev Library and Reading Room. The book is dedicated to the memory of Gottfried Kratz (1947–2022), a renowned German Slavist, librarian, researcher of the history of Russian book publishing abroad, and a member of the editorial boards of the journals Bibliography and Bibliography and Bibliology, as well as the encyclopedia Germans of Russia. The book under review includes information about the life and work of G. Kratz, the memoirs of relatives and colleagues, and the scholar’s articles on I.S. Turgenev.
