Emphasis is on the 19th century to the present. Materials covering earlier periods are collected selectively to include support for teaching and research on political thought from antiquity to the present, as well as other historical concerns such as political philosophy, historical comparative politics, and the historical development of states and other entities.
Print and electronic books and journals are primarily collected. Video is also collected on an as-need basis. Periodicals are e-preferred. Videos are purchased as DVDs or video files with perpetual streaming rights when available and affordable. However, content will be purchased in any format as conditions require. Textbooks are not considered unless requested. The same applies to pamphlets, with the exception of topics such as major policy statements and political party platforms.
The United States, Europe, East and South Asia, the Middle East, and Sub-Saharan Africa are heavily represented.
English language publications from the United States and Great Britain followed by those of the major Western European languages are collected. Materials in other languages, particularly in areas where Penn has historical strengths or ongoing research, are obtained selectively. Non-western language materials from the Middle East, South and East Asia, the Soviet Union, and Eastern Europe are collected by area studies bibliographers.
