LexisNexis traces its origins to 1970, with the LEXIS legal research database publicly launched in 1973 — making it one of the oldest and largest legal information platforms in existence. Owned by RELX Group, LexisNexis serves law firms, corporations, government agencies, and academic institutions globally, maintaining what has been described as the world's largest electronic database for legal and public-records information. The platform employs over 10,000 people worldwide.
Core capabilities include full-text case law retrieval across all U.S. federal and state courts, Shepard's Citations for verifying precedent status, statutory and regulatory research, secondary sources such as treatises and practice guides, news and business intelligence, and public records search. The platform has expanded with AI-assisted research tools and integrated analytics features for litigation analytics and brief analysis.
LexisNexis differentiates itself from Westlaw primarily through Shepard's Citations (versus Westlaw's KeyCite), its depth of public records data, and its integration of legal and business intelligence in a single platform. It also offers Lexis+ AI and Lexis Protege as AI-enhanced overlays, though the core LexisNexis platform remains the foundational research environment.
Best fit: Large law firms, in-house legal departments at major corporations, and government agencies that require comprehensive multi-jurisdictional research, deep secondary source access, and integrated business intelligence. Budget-sensitive solo practitioners or small firms may find pricing prohibitive relative to alternatives.
