The United States Code and most state codes are available for free online. These sources usually only provide the text of the statutes, however, and do not include annotations or case references. The online versions of codes also may not be current, which means they may not reflect the changes made by more recent legislation. Researchers therefore need to be careful to update these code sections with relevant case law and session laws.
For information about finding relevant statutes and statutory law generally, please see our Finding Statutes Guide.
These sources contain the most recent official version of the U.S. Code, which is published every six years. As a result, some individual code sections will be out-of-date and these sources need to be updated with session laws. As noted in the table below, the version provided by Cornell's Legal Information Institute provides links to recent legislation so researchers can easily determine how a particular code section has changed since the last official publication.
