Legal research terms can sometimes be confusing. If you can't remember the difference between a cited case and a citing reference, between primary authority and mandatory authority, or between session laws and a statutory code, check the law library's Glossary of Legal Research Terms or one of the references listed at the bottom of that page, all of which are available in the law library or on the web.
