Ginsburg withdrew as an editor at "Der fraynd" in 1908 and in the following years devoted himself more fully to studies of the political, social, and cultural history of Russian Jewry. In 1913 he published a study of Russian Jews at the time of the invasion of Russia in 1812 during the Napoleonic Wars ("Otechestvennaya voina 1812 goda i russkie yevrei"). He also co-edited the Russian-language journal "Perezhitoe" (1908–1913), which specialized in the publication of primary sources for Russian Jewish history.
