The collection consists of papers relating to Enright's role as theatrical agent to performers, many of whom were and are well-known, as well as to aspiring actors and actresses. The collection includes legal contracts (originals and carbons), correspondence of Enright, miscellaneous material containing commission receipts, and playbills. The correspondence contains requests for interviews by young performers, announcements by actors of their imminent return from military service during World War II, requests to be "kept in mind" by clients whose present plays are ending, cover letters in which commission checks are enclosed, and friendly letters by long-term clients. Besides actors and actresses, the correspondence includes letters from producers such as Moss Hart, Howard Lindsay, Russel Crouse, Brock Pemberton, and Richard Aldrich. Some of the older performers represented in the collection are Madge Evans, Zasu Pitts, Monty Woolley, and Louis Calhern.

In addition, there is correspondence by newcomers in the 1940s who went on to have outstanding careers, such as Geraldine Page, John Forsythe, and Philip Bourneuf, as well as letters by Jocelyn Brando and Betty Caulfield about their siblings, Marlon Brando and Joan Caulfield, whose careers later eclipsed their sisters'. Paul A. Foley, stage manager, actor, and director, is well-represented in the collection.
