This collection contains correspondence, sermons, personal notes, and photos of Dr. William McCutchan Morrison. The majority of the letters were written by Morrison to his mother, Mary A. Morrison. A number of letters were written by him to his siblings. Miscellaneous family papers are included as well, such as a letter by an unidentified Liberty Hall Volunteer. The correspondence is largely about his dealings and life in Congo, primarily regarding his missionary work. The included photos are of life in Congo during the missionary work of Morrison. Researchers should be advised that the collection includes images of the Congolese people which bear witness to the physical brutality they suffered under the regime of King Leopold II of Belgium. The sermons are Dr. Morrison's theological teachings. Some sermons were written in what Morrison described as the "native" language.

This collection guide does not account for the various artifacts that were donated alongside the papers. The artifacts will be assessed and described at a later time. They include a Congolese shell-beaded mask, textiles, a carved decorated wooden cup, Congolese bow and arrows, iron arrow points, iron spear point and a hatchet and other small items. There is also an American Civil War period Confederate manufactured leather cartridge box and sling likely used in the Civil War by Morrison's father James L. Morrison or more likely his uncle Heny R. Morrison who served in the Washington College's Co. I, 4th Va. Infantry.

Morrison's iron trunk for his papers while in Belgian Congo is also included in the collection.
