The Trisha Brown Archive follows Trisha Brown's mandate to treat the Company’s archive as a living organism to be used to better understand her work, in particular, and dance in general. In 2009, the TBDC Board of Trustees formalized the creation of the Trisha Brown Archive, under executive director Barbara Dufty's stewardship to initiate the cataloguing and preservation of Trisha Brown’s oeuvre. The archive provides a comprehensive record of Brown’s creative process and legacy, with an interdisciplinary focus reflected in the scope of the material. TBDC holds significant archival material, including extensive moving image footage and audio recordings, notebooks and scores, photographs and posters, sets and costumes, performance programs, clippings and organizational files, as well as Trisha Brown’s personal notebooks and records. In addition to items documenting Brown’s creative work, the archive also includes evidence of Brown’s collaborations with artists who are themselves leaders in music, theater, and the visual arts, including Robert Rauschenberg, Donald Judd, Nancy Graves, Elizabeth Murray, Terry Winters, Laurie Anderson, and John Cage, among others.
