Art21 maintains an extensive library of all of the films and educational materials it produces. The core of the Art21 Library is nearly one thousand hours of original documentary footage amassed during the production of Art21’s films. Art21 continues to film with previously featured artists, documenting art installations, exhibitions, and performances at galleries and museums worldwide. The Art21 Library also includes film documentation of Art21’s education and public programs, including hundreds of hours of video by Art21 Educators participants. The filmed material in the Art21 Library is supplemented with transcribed interviews, research materials, educational publications, Web pages, books, and digital and analog artwork reproductions.
