Internet Legal Research Weekly describes the Oyez - U.S. Supreme Court Multimedia website:
Developed by some folks at Northwestern University and others, Oyez, is a multimedia guide to the U.S. Supreme Court. It contains over 2000 hours of Supreme Court audio, from cases dating back to 1995. Here you'll find info on the cases being argued before the Supremes, as well as links to other authoritative Supreme Court sites. Oyez makes good use of other Supreme Court resources, like the Supreme Court Podcast, memos from Mayer, Brown & Platt, and Justia's Supreme Court Center.
