Federal and state case briefs are generally available on Westlaw, LexisNexis, and Bloomberg Law. In Westlaw, when viewing a case, click on the Filings tab at the top of the screen. In LexisNexis, briefs are available in the right column while viewing a case. In Bloomberg Law, when viewing a case, click on the "General Info" icon on the right margin and then the appropriate link under "Related Dockets" to get to a docket sheet with links to request or view briefs and other pleadings.
For federal cases, check for coverage in Westlaw, LexisNexis, and Bloomberg Law. If a document is not available in any of the databases, it may be available in PACER (Public Access to Court Electronic Records). The law library has a subscription to PACER but because charges are incurred for accessing documents, a law librarian must mediate a PACER request. Find the docket number and date of the document from the article, or try searching the court’s website or Google.
