LA Law Library's CA Appellate Briefs (some available digitally)
The LA Law Library has a large collection of California appellate court briefs and (with help from LLMC) is digitizing the briefs of California appellate and Supreme Court cases. When the project is complete, it will include briefs from the beginning of the California Court of Appeal (1905) and the California Supreme Court (1850). Because one needs the docket number to search for briefs, please go first to the California Appellate Courts Case Information page (http://appellatecases.courtinfo.ca.gov/) where one can search by party name, attorney name, and/or case caption (after selecting the court).
Briefs in that collection from 1995 to present are now available digitally at this site: http://briefs.lalawlibrary.org/research/default.aspx.
Briefs in that collection that are not yet digitized can be obtained digitally for a modest fee. They provide a scanning and e-delivery service: http://www.lalawlibrary.org/index.php/services-rentals/e-delivery.html.
