This legal research exercise book helps students master efficient legal research skills through hands-on problems. The revised 12th edition contains fifteen assignments, with updated problems from the twelfth edition. Each assignment, except Assignment Ten, contains four variations: two variations using the print materials, one exercise using Westlaw, and one exercise using Lexis Advance. This format provides instructors more flexibility in what exercises they assign and when they assign them. The assignments cover basic legal research, including reporters, digests, citators, statutes, and advanced materials including federal legislative history and federal administrative law. There are also review problems, appropriate for basic and advanced legal research classes. The revised edition's questions/answers follow the 20th edition of The Bluebook: A Uniform System of Citation (2015).
