These are mostly sorted by medium, not subject, as a lot of the subjects overlap and I don't want to list the same link multiple times. I'm trying to list them within each section in order of most general to most specific. Use your judgment about the reliability of a site or on whether or not it would be acceptable to cite for a paper.

- Librivox is a website where volunteers read and record public domain works. These recordings are also availible on the Internet Archive.
- Oxford University posts a surprisingly high amount of podcasts
- La Trobe University released a variety of podcasts, but I'm unable to find a link to a list of all of them.
