Except where noted, the letters are original letters to Percy Muir and carbon copies of letters from him. The title of the item is the name of the correspondent. Some of the correspondents were Muir's collaborators (including John Carter, John Dreyfus, H. A. Feisenberger, John Lansdell, Jack Matson, Howard M. Nixon, David Randall, S. H. Steinberg). Most of the others were prospective lenders to the exhibition. Except for item 87, the letters generally cover the time before the exhibition itself.
