Best Legal Research 2026 - Frequently Asked Questions
What is the most comprehensive legal research platform?▾
Westlaw (Thomson Reuters) and LexisNexis are the two dominant comprehensive legal research platforms — both offer extensive case law databases, statutes, regulations, secondary sources, and citator services (KeyCite and Shepard's respectively). Both are expensive and primarily accessed through law firm or law school subscriptions. Fastcase and Casetext offer lower-cost alternatives. Google Scholar provides free case law access for US federal and state courts.
What is a legal citator and why do lawyers use them?▾
A citator tracks how a case has been treated by subsequent courts — showing whether a case was affirmed, distinguished, questioned, or overruled. KeyCite (Westlaw) and Shepard's (Lexis) are the two primary US citators. Citing a case without checking its current validity is a significant professional error — an overruled case cited as good law is a basic research mistake. Citator use is a non-negotiable step in legal research.
What are free legal research tools?▾
Google Scholar provides free access to US federal and state court opinions. CourtListener (RECAP Archive) has millions of free federal court documents. Legal Information Institute (Cornell LII) provides statutes and regulations. Justia provides free case law and legal resources. Free resources are adequate for many research tasks; the Westlaw and Lexis advantage is comprehensive secondary sources, superior search relevance, and authoritative citator tools that free options lack.
