This collection consists of original correspondence and other secondary source material on Hannah More, gathered by Mary Alden Hopkins in the course of her research for the book Hannah More and Her Circle (1947). Materials include original outgoing letters from and incoming letters to Hannah More, typescripts of letters in this collection, copies and transcripts of More letters and materials held by other institutions, correspondence between Hopkins and various scholars and librarians, and three early works by More from Hopkins' collection (the majority of Hopkins' Hannah More book collection has been at Barnard College since 1975).
