Bringing together research material, rehearsal notes, and scripts with programs, flyers, and reviews, this series documents the entire creative process from a project's conception to its performance before an audience. Each of the theatre's major productions is represented, and often times individual performances of these productions, demonstrating how they have evolved over time.

Beginning with the group's first production, , which later became part of the , through and , this series also provides a record of their artistic growth and thematic movement. Over the years, Double Edge has changed, but they have always stayed true to their mission of training, research, performance, and cultural exchange.

Double Edge Theatre has been involved in international study, exchange, and collaboration since its earliest days. Their first major collaboration was with Poland's Gardzienice Theater Association, a collaboration that since 1986 has included producing one another's work, hosting pedagogical sessions, symposia, and creating projects together, such as . This series documents the theatre's collaborations with Gardzienice as well as with many other theater companies around the world and in the U.S., including Odin Teatret, Diablomundo, Charlestown Working Theater, and Women in Theater Festival/Next Stage. Also covered are cultural exchanges seminars and symposia, residences and research, as well as international guest artists performing with DET.

This series consists almost entirely of correspondence between Double Edge and other artists or companies from around the world. Critical to understanding the development of the theatre are the correspondence, speeches, and writings of Stacy Klein, founder of Double Edge. There is some overlap between the correspondence series and the other series in this collection, in particular, Series 2: Theaters and Collaborations. Many of the proposals and exchanges discussed in the letters found here were later developed into the projects and collaborations documented primarily in series 2. For the most comprehensive view of the evolution of projects from research to performance, both series should be consulted.

Dealing chiefly with the more prosaic details of operating a theatre group, this series includes records that reveal details about the company's day-to-day activities, covering financial, legal, and fundraising aspects. Minutes of meetings from the early years of the theatre are of particular interest as well as the notes and financial records documenting the formation of the Conversation project, a symposia for directors from Central Europe and the U.S. which concluded in a public forum for fifty arts professionals.

The series consists mostly of photographs of Double Edge productions and collaborations, again documenting the evolution of their productions. Beyond capturing the staged performances of the theatre's work, though, this series also includes images of the company's training and life on the Farm, providing a unique behind-the-scenes look at this artistic community.
