During a course revision earlier this year, a member of the Extension Instructional Design Team made me aware of Internet Archive. It describes itself as “a non-profit library of millions of free books, movies, software, music, websites, and more.”

It’s something of a resource of resources that’s user-friendly to navigate. There’s community-uploaded content alongside material from physical libraries and hosts of other sources. You can look through video, audio, patents and trademarks, journals, and even video game speed runs. Especially interesting is their Wayback Machine, their archive of websites as they have appeared throughout the years.

You can explore Internet Archive at:
archive.org

Internet Archive also allows you search for media based on its distribution rights (for example, if it’s in public domain). To learn how, go to:
