This newly updated law school textbook and course reference is designed specifically for advanced legal research classes and for upper-level students who want to achieve a better understanding of how to use the sources of legal information that they learned about in their introductory courses. It provides in-depth guidance through the research process, advice on format selection, and detail about the tools and techniques needed to function as skilled legal researchers. Up-to-date discussion of all media is fully integrated throughout, focusing on the types of information the researcher needs, rather than on descriptions of particular information products.
