The collection consists of correspondence, the manuscript of the play "Milestones", two manuscripts of essays published in the London Evening Standard, notes for the play "Mr. Prohack", and a binder of clippings about the run of "Milestones". The chief correspondents are Arnold Bennett, Edward Knoblock, and Max Meyerfeld. The Bennett-Knoblock correspondence concerns agreements and rights pertaining to "Milestones", the writing of two other plays, "London Life" and "Mr. Prohack," Knoblock's experiences in Hollywood, and their shared hobby of furniture buying. The Meyerfeld-Knoblock correspondence concerns the translation of "Milestones" into German. All letters are indexed.
