Winner of the American Association of Law Libraries' Joseph L. Andrews Legal Literature Award in 2010, Principles of Legal Research provides encyclopedic yet concise coverage of research methods and resources using both free and commercial websites as well as printed publications. It has been thoroughly updated to provide coverage of WestlawNext, Lexis Advance, Bloomberg Law, and other new resources. An introductory survey of research strategies is followed by chapters on the sources of U.S. law created by each branch of government, discussion of major secondary sources, and an overview of international and comparative law. Sample illustrations are included, and an appendix lists more than 500 major treatises and looseleaf services by subject.
