Organization of American States is the world's oldest regional organization
dating back to the First International Conference of American States held in
Washington, DC in 1889-1890. The first office established by this new
organization was a library and archival repository that was named the Columbus
Memorial Library. This library houses the world's most complete collection of
unique photographs, maps, commemorative stamps, archives, and records
documenting the history of the Organization of American States and its
predecessor agencies from 1889 to the present. The extensive collection of books
and periodicals date back to 1535. The library holds one of the richest
repositories for material on the Inter-American system in the world.
