{"value"=>"<p>The Publication Files subseries contains the photographic collection of the <span class=\"title\">Review of Reviews</span> and the <span class=\"title\">Literary Digest</span>, which was purchased by the <span class=\"title\">Review of Reviews</span> in 1937. Photographs in this subseries remain in the topical division established by the publishers: Individuals, Geography, and Subjects. Topics of the photographs encompass current events, political analysis, social and economic commentary, contemporary culture, and technological advances during the early decades of the twentieth century. These materials are primarily copy prints, and most were acquired from the principal news services active at the time (including Acme, Blackstone, Keystone, Underwood and Underwood, and the American Press Association).</p>"}
