The content, legends and methods of designing the basic soil maps in complex regional atlases published over the past 60 years were analyzed. The atlases were grouped in accordance with the time of publication and potential users. The main attention was paid to the content and conceptual background of maps, their compliance with the rules and experience of traditional soil mapping in Russia, as well as to the requirements for soil maps, i. e. completeness of information with new knowledge included, visual clarity and readability. The content of maps is assessed in the following aspects: natural soils, presence of human-modified soils, classification used, soil cover composition and pattern, relief, and soil texture. The legends were evaluated in terms of information on soils and presentation of the mapping concepts, namely, legend structure, the number of units and the order of soils in the legend; methods of cartographic presentation were discussed as well. Soil maps in the atlases dating from the second half of the last century were compiled in accordance with the zonality concept; the soils basically corresponded to the USSR soil classification (1977) with some additions. In the atlases of the latest period, there are several maps compiled according to the new classification of soils in Russia. Soil maps in the atlases mostly used standard cartographic techniques; at present a certain deviation from the rules and standards of traditional soil cartography is obvious, which affects the information content and visual clarity of maps
