The Archives of the American School consist of two repositories, separately housed but jointly administered by the Archivist--that of the Blegen Library and that of the Gennadius Library.
The Archives in the Blegen Library comprise administrative records related to the function and mission of the American School, excavation records from American archaeological projects in Greece, and personal papers of American archaeologists and architects working in Greece; scholars such as Carl W. Blegen, Gorham P. Stevens, William B. Dinsmoor, Virginia R. Grace, and Homer A. Thompson. There are also extensive holdings of photographs of Greece and excavations in Greece during the early years of the American School. The Antiquities Collection of the American School is another one of its valuable resources with a large body of artifacts from a large number of sites in Greece, as well as Anatolia, Cyprus and Egypt.
The Archives in the Gennadius Library contain many collections of personal papers that contribute to an understanding of political developments from the 18th to the 20th century in Greece and the Balkans (such as the papers of the founder of the Library, Johannes Gennadius, those of the Dragoumis Family, the papers of Stephanos Skouloudis and Konstantinos Mousouros, and others). The Gennadius Library also collects the papers of important Greek literary figures, including the papers of the Nobel prize-winning poets George Seferis and Odysseas Elytis, novelists Stratis Myrivilis and Angelos Terzakis, and philhellenes such as Heinrich Schliemann, the excavator of Troy and Mycenae. In addition, the Gennadius Library holds the papers of renowned orchestra conductor Dimitri Mitropoulos.
