Chatto and Windus, Clarke, Irwin and Company, Toronto Star Syndicate, Viking Penguin, and Weidenfeld & Nicolson) and others by literary agent (A.P. Watt & Son and Willis Kingsley Wing).

Dominion Drama Festival, Eastern Ontario Drama Festival, Kitchener-Waterloo Little Theatre, Lennoxville Festival, Montreal Repertory Theatre, National Arts Centre, Peterborough Little Theatre and Stratford Festival) and files on other organizations (eg. Canadian Authors' Association, Canadian Society for Italic Handwriting, Opera Festival Association of Toronto, and the University of Toronto). Some of the correspondence is organized by the title of Davies' work to which it refers (eg. At My Heart's Core, Diary of Samuel Marchbanks, The Manticore, etc.) and there are extensive files on his years with the Peterborough Examiner. Finally, some of the correspondence is organized in general alphabetical files (eg. "Correspondence H-L", some in "General" files and some in "Personal" files.)
