If you can't find what you're looking for online through a free or subscription database, consider checking the law library's collection of U.S. Supreme Court Records and Briefs available on microfiche. The microfiche collection covers full opinions (1832-2012/2013) and cert denied (1832-2010/2011). In addition, the National Archives is a great resource for hard-to-find Supreme Court documents; for example, they have audio recordings of oral arguments from 1955-Present, oral argument transcripts, as well as dockets from 1791-Present.
