Public Performance Rights from http://www.vdb.org/content/license-agreements#Educational

Material may be used for cultural or institutional use only. Materials may be screened in classrooms, libraries or screening venues on the premises or property of the purchasing institution.

Educational purchase from the Video Data Bank comes with "public performance rights" which the law defines as the "right to screen at a place open to the public or at any place where a substantial number of people from the public who are not necessarily affiliated with the purchasing institution are assembled". However, extended exhibitions or looped display within museums and/or galleries that are part of the purchasing institution are NOT permitted.

The purchasing institution has the right to charge admission fees to the general public.

The purchasing institution cannot lend, rent, sell or otherwise disseminate the materials to another cultural or educational institution, the general public or any other third party for institutional or home use or for use outside of the purchasing institution including the use in touring programs. This provision supersedes all First Sale Doctrine rights.
