The collection includes Corey's scripts, personal and business correspondence, clippings, programs, photographs, posters, lobby cards, audio tapes and videos. A significant part of the collection is devoted to materials Corey used to teach his acting classes, including script excerpts, notes on acting theory, lesson plans, charts and notes on student progress. There are also extensive papers and clippings related to the House Un-American Activities Committee (HUAC) including Corey's summons to appear before the committee, a copy of Corey's prepared statement to HUAC (that he was never allowed to deliver), and a transcript of testimony given to HUAC by Rose Hobart, Roman Bohnen, J. Edward Bromberg and Will Lee of the Actors' Lab on February 17, 1948.
