Obtaining a public performance license for a film is relatively easy and usually requires no more than an email or phone call. Fees are determined by such factors as the number of times a particular movie is going to be shown, how large the audience will be and so forth. While fees vary, they are generally between $200-400 per showing.
Note on documentaries: Some of the documentaries that have been purchased for Skillman’s collection came with public performance rights. This means that can be shown on campus anytime without needing to call or pay extra for permission (subject to certain limitations, of course). Look for rights information on the video label, container, on the screen or contact the research help department at email@example.com or call (610) 330-5155.
