It consists of a miscellany of letters, notes, legal documents, cartographic materials, genealogical materials, photographs, newspaper clippsing, other printed material, and other types of documents. Although tehc ollection largely concerns Stevenson, it also includes some material of her husband, James Stevenson, and members of her family, especially her father, Alexander H. Evans, a Washington, D.C. attorney.
Many of the documents concern Stevenson's field work among the Pueblo Indians and other official duties with the Smithsonian. some material relates to her activities with the World's Columbian Exposition and the Louisiana Purchase Exposition. A few items concern her membership in scientific organizations. Still other documents are of a personal nature, and some are mementoes, especially of James Stevenson. A significant group of documents concern Matilda CoxeStevenson's friendly and, later, very difficult relationship with Clara True.
