The collection consists largely of items removed from books in the Harrisse Collection in Special Collections at Johns Hopkins dating from approximately 1876-1910, as well as correspondence about Harrisse after his death, dating from 1937-1941. Henry Harrisse was a noted scholar and bibliophile, and some volumes from his library form part of the collections of The Johns Hopkins University. The items were inserted directly into the books and have been separated to form the manuscript collection. These materials are arranged by the call number of the book from which they were removed. Included are letters, newspaper clippings, calling cards, invitations, and notes. Harrisse was acquainted with distinguished authors in 19th- century Paris including Ernest Renan, George Sand, Alexandre Dumas and Charles de Spoelberch de Lovenjoul. Apparently, it was his habit to insert some memento or reference into his personal copy of a published work. For instance, in George Sand's Lettres d'un Voyageur was an invitation to a puppet show from M. and Mme. Maurice Sand. A newspaper review (1874) was included in Dumas's L'Ami des Femmes. More recent material in the collection is correspondence, 1937- 1941, of Albert U. Walter, a great-nephew of Harrisse and resident of Baltimore. Maryland. Correspondents include Randolph G. Adams, who did a profile of Harrisse in Three Americanists, and Richard H. McMaster who wished to acquire a photograph of Harrisse for the Mt. Zion Institute in Winnsboro, South Carolina. A final item in the collection is a photostat of a short title list of Harrisse's bibliographical writings.
