Computer-assisted legal research (CALR)[1] or computer-based legal research is a mode of legal research that uses databases of court opinions, statutes, court documents, and secondary material. Electronic databases make large bodies of case law easily available. Databases also have additional benefits, such as Boolean searches, evaluating case authority, organizing cases by topic, and providing links to cited material. Databases are available through paid subscription or for free.[2]
Subscription-based services include Westlaw, LexisNexis, JustCite, HeinOnline, Bloomberg Law, Lex Intell, VLex and LexEur. As of 2015, the commercial market grossed $8 billion.[3] Free services include OpenJurist, Google Scholar, AltLaw, Ravel Law,[3] WIPO Lex, Law Delta and the databases of the Free Access to Law Movement.
