This legal research exercise book helps students master efficient legal research skills through challenging in-depth problems. The 10th edition contains all new problems and a new format covering both print and electronic resources. Assignments have two variations using print materials, one variation for Westlaw, and one variation for LexisNexis. 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.
