Oyez Project SCOTUS MP3 files

This site has mp3 files of the oral arguments in many important older decisions: Miranda v Arizona (1966), Roe v Wade (1973), NY Times v US (1971, the Pentagon Papers case), Loving v Virgina (1967), and a number of less famous cases. These files are large, and not always very clear.

2020 Update: Oyez reoganized. The cases are still there, and not just important ones, but you have to search for them. Loving v Virgina, for example.
