### Description of your *issue*, suggested solution and other information

[Kanopy](https://kanopy.com) is [very popular with libraries in the US](https://www.nytimes.com/2017/08/24/watching/kanopy-criterion-collection-library-card.html), most notably the [NYPL](https://www.nypl.org/). You should check to see if [your local library](https://www.kanopy.com/wayf) is supported. Anyway, Kanopy is a treasure trove of educational and/or [public domain films](https://en.wikipedia.org/wiki/Public_domain_film#United_States) and would be an excellent supported site addition to this already excellent app. THANK YOU!
