The review features a high assessment of the monograph by A.V. Novikov. Its publication was an important milestone in the study of Early Iron Age antiquities from the Kostroma Volga region. The author of the monograph systematized the extensive material, part of which was obtained as a result of his own field investigations. The significance of the publication is associated with the fact that the study of the sites of this historical period is closely related to the issue of the genesis of the Volga and Baltic Finns, which remains a highly arguable study topic. A.V. Novikov concludes that the origin of the sites with the comb-corded and corded ceramics in the region is associated with the migration of the Ananyino population from the Upper and Middle Vetluga region. The appearance of such ceramics corresponds to the 6^th century B.C. Local traditions of the representatives of the textile ceramic culture was predominant in the region during the subsequent periods. The review focuses on arguable topics. In particular, it questions the correspondence of a number of sites with no flat-bottomed ceramics to the Iron Age. Early materials from the Kostroma Volga region are considered as belonging to the Dyakovo-Gorodets type. The appearance of comb-corded and corded ceramics in the region is associated with the impact of the bearers of Akozino antiquities.
