As we've mentioned in the past, Archive.org hosts some wonderful free, public domain media. Many of their classic films appear in our collection of Free Online Movies. And they also provide access to lots of free public domain music (including a large Grateful Dead concert archive). Thanks to a new site, Dewey Music, you can now sort through this extensive music catalogue with greater ease and find the free gems faster. Dewey Music was created by six industrious college students, and we thank them.
