MAP ADVERTISEMENTS AS HISTORICAL SOURCES

High research potential of maps and advertisements was recognized by scientists for a long time. The majority of research investigations contain analysis of separate documents. If a map contains an advertisement, it provides more opportunities for investigation. The purpose of the article is to reveal the research potential of maps containing advertisements. The author studied a map of Asian part of Russia and Turkestan Krai kept in the collection of Omsk State Library named after Alexander Pushkin. The research enabled the author to identify the time when the map was published (1901-1904), reveal the specifics of advertised goods and their manufacturers, and outline the supply geography and target audience of the advertised products. The author concludes that advertisements enhance the potential of maps as historical sources.
