This series includes photographs, lecture schedules, and promotional brochures for Hillis's speaking engagements and publications. Also included are Plymouth Church bulletins, programs from tributes to Hillis, and assorted brochures relating to people and organizations with whom Hillis was involved. Folder 1 contains a biography of Hillis titled 25 Years at Plymouth Church, which appears to have been written by his secretary, Lucie L. Whitlock, upon his resignation from the Church.
The letter collection which is filed here contains assorted letters from Henry Ward Beecher, Booker T. Washington, and others. Most of these letters are not addressed to Hillis. A few have notes by Richard Hillis attached.
