Hoopladigital is a relatively new media streaming service "... that partners with your local public library to bring you thousands of movies, television, music, and audiobook titles for free. There are no costs or hassles. All you need is a library card and a web browser, phone, or tablet."
Here's the current lineup of participating libraries:
The Boston Public Library system just joined, so most of eastern Mass. now has free streaming available. :) The library systems in Chicago and Toronto are just about to come online, with many more in the works.
You can sign up and view/hear movies and music using your browser at https://www.hoopladigital.com/; free apps are also available for iOS and Android.
If your library participates, check it out! If your library doesn't, maybe you should ask why!
