This collection contains both professional and personal documents of Anthony Koo, dating from the 1940s through the 1990s. A significant portion of the collection is composed of materials relating to the post-World War II Far Eastern Commission (FEC), including press releases, meeting agendas and minutes, and informational materials circulated among committee members. Several other FEC-era documents address these issues as well, but are not "official" FEC materials. Koo's involvement in International Labour Office projects is also included in a portion of this collection. The other significant professional component of this collection includes materials relating to Koo's time as a professor of economics, primarily at Michigan State University. These documents include several articles authored by Koo himself, as well as articles by other authors related to his work and documents from the Department of Economics. Finally, there are some personal documents included in this collection, including some personal correspondence, a grade report from The George Washington University, and documents from Chinese student organizations of which Koo was a member.
