Scope and arrangement
The Music Files, comprising the great bulk of the collection, consist primarily of scores, including reduction scores, full scores, specific instrument parts, chorus scores, and lead sheets. Some song lists, lyric sheets, arrangement notes, theatrical scripts, and published sheet music are also present in this section. Most of this material relates to theatrical performances and musical concerts. Some relates to arrangements Harper created for musical recordings or production work he performed for albums, including Broadway cast recordings. Collaborators include Barbara Cook, Sherman Yellen, Malcolm Gets, Tommy Tune, and David Zippel. Music Files are arranged alphabetically by production title, collaborator name, or subject.
The few Scrapbook Files hold photographs, invitations, letters, and some news clippings.
The Audio and Moving Image Files include audio recordings of music by Barbara Cook, Tommy Tune, Nathan Lane, and The Pointer Sisters; audio relating to rehearsals or performances of Gypsy, The Best Little Whorehouse Goes Public, Josphine Tonight!, Say Yes!, and Lucky in the Rain; video of a Grand Hotel workshop performance; videos of a performance at the White House, and various television appearances by Barbara Cook. Audio and moving image recordings are unavailable pending digitization.
