For upper-level law students, law clerks, and attorneys, Paul D. Callister’s Field Guide to Legal Research (West Academic Publishing, Mar. 11, 2019) “is not another exhaustive treatise but a concise, working person’s guide to solving complex legal research problems. Much like a field guide, this book classifies problem types and matches them with appropriate legal research resources. It emphasizes “working the problem,” “problem typing,” and then application of problem types to the appropriate resources. Problems and exercises illustrate the application of constructs and techniques to particular situations. Coverage is much broader than in first-year legal research classes. The book includes problems based on government agencies, statistics, and even patent law. There are numerous “screen shots” and images to facilitate the learning process.” Recommended.
