The law school library maintains current versions of West regional reporters for access to all states' case law in print.
Online access to case law for all states is also available via subscription to Westlaw and LexisNexis. South Carolina colleges and universities and public libraries may subscribe to academic and public versions of Westlaw and LexisNexis. The University of South Carolina provides access to case law for all states through its subscription to LexisNexis Academic.
States typically provide access to several years of appellate court opinions on their judicial system websites. The National Center for State Courts maintains a State Court Web sites page. Other free sites that provide access to all state court opinions include Cornell University's Legal Information Institute's Listing by Jurisdiction; FindLaw’s Cases and Codes; Fastcase’s Public Library of Law; and Google Scholar.
Free websites may allow you to choose a single state, search multiple states or search all state case law at once. Free websites, however, do not include headnotes and other enhancements to cases available through paid subscription databases.
