You have been asked to find different formats of primary sources (visuals, maps, information about people, and data). You will find these kinds of primary sources spread across and within different resources. Sometimes you wil look in a database of images, sometimes you will find images in a printed book or a newspaper. Sometimes you will find images and data in the same source. Maps may be online and interactive (and build your own) or they may be static and printed. Much of what you will find will not be digital. Even if it is digital, it may be hard to locate. Below are some sources to get you started. There are many more I could have added depending on your topic of research. Also check out other guides listed below for more recommended primary sources.

Pravda ("Truth") was the official voice of Soviet communism and the Central Committee of the Communist Party between 1918 and 1991. Founded in 1912 in St. Petersburg, Pravda originated as an underground daily workers' newspaper, and it soon became the main newspaper of the revolutionary wing of the Russian socialist movement. Throughout the Soviet era, party members were obligated to read Pravda. Today, Pravda still remains the official organ of the Communist Party of the Russian Federation, an important political faction in contemporary Russian politics.
