The Margaret Croyden papers contain writings, research material, photographs, audiovisual material, and personal papers. Writings include drafts, printed versions, and photocopies of printed versions of reviews and essays on theater-related topics as well as corrected drafts of her fourth book, The Years in Between (Xlibris, 2011). Video recordings appear to date chiefly from Croyden's tenure with the CBS TV series Camera Three during the 1970s. There are audio recordings and other materials relating to theater director Peter Brook and possibly to Croyden's Conversations with Peter Brook: 1970-2000 (Theatre Communications Group, 2003). Other materials in the collection include clippings, computer disks, correspondence, photographs, a laptop, and slides.
