The best place to start is the database
Making of Modern Law: U.S. Supreme Court Records and Briefs, 1832-1978 A digital collection of more than 240,000 documents on more than 100,000 U.S. Supreme Court cases. It is a valuable database of primary source documents, as well as material presenting the background and context of the cases. This collection covers the Supreme Court from the final years of the fourth chief justice, John Marshall, through the first ten years of the court's 15th chief justice, Warren Earl Burger.
If the database does not have the case you need, The Supreme Court
website lists sources for briefs, including amicus briefs.
Groups and interested parties often post amicus briefs on their websites. Using Google, type the short name of the case and amicus. For example, typing Heller AND amicus brings up the NRA's brief, Cato Insitute, SCOTUSblog and more on this landmark gun control case.
Some briefs may be included in books on the court case.
Check with the
Pence Law Library of the Washington College of Law for assistance in finding briefs from lower courts.
