Most of this series is from the mid-90s through mid-2000s, after Eastman’s retirement from Gallaudet. It includes correspondence, programs, agendas, and advertisements for speeches he gave and sign language workshops he conducted around the country. In some cases, his text and/or notes for his presentations are also included. Venues include deaf and hearing schools and conventions of deaf groups.

Correspondence files from Eastman’s time as chair of the Gallaudet theater department, arranged alphabetically by subject. Bulk is from the mid-1970s through early 1990s. Includes correspondence, clipping files on prominent deaf actors, material on deaf theater, and some dissertations and theses. Of particular interest are correspondence files for Deaf Mosaic (series 5 has more on Deaf Mosaic) and a file on Eastman’s book From Mime to Sign.
