Cornell Law School’s Legal Information Institute (LII) includes a page with a wealth of information, including definitions and summaries of legal concepts and subjects such as contract law and tort law. It clarifies the meaning of nuanced terms like “Malpractice ,” which is a species of tort, saying “The tort committed when a professional fails to properly execute their duty to a client.”
The Legal Information Institute also includes the U.S. Code, many case decisions and state legal resources.
