Rwanda.

Bob Campbell is best known for his success encouraging and filming the first peaceful close encounters between a human and mountain gorillas, as part of Dian Fossey's conservation and primatology field research at the Karisoke Research Center in Rwanda, Central Africa. The bulk of the collection is Bob Campbell's professional photographic work, primarily on the subjects of African wildlife and orchids, with an emphasis on East African species.

The Lemarchand Collection includes copies of official reports and other documents assessing political situations and events, newspapers from several countries, and copies of unpublished studies and reports. Countries covered include Rwanda, Burundi, Zaire, Chad, and to a much lesser extent Gabon and Libya. Chad is the most extensively covered; the Zairian and Libyan materials are limited to newspapers.
