I have found this book quite helpful in translating my scholarly research and writing skills into legal research and writing skills. Though intended as a textbook for courses, I have also found it a nice resource in my part-time job as a law clerk at a firm. The authors have taught courses in legal assistance and parallel fields, so the book is quite practical—something one does not always receive in law school. Especially in a research degree such as mine. From the Amazon page:
Comprehensive yet easy to understand, the third edition of LEGAL RESEARCH, ANALYSIS, AND WRITING teaches the fundamentals in a hands-on, step-by-step format that is designed to build confidence. With coverage of key topics such as research analytical principles, legal research, legal analysis, and legal writing, this popular book covers the information readers need to know in order to find, access, apply, and analyze legal materials. Numerous hypotheticals, examples, and exercises clarify material and give readers additional opportunities for practice. In addition, the third edition includes the most up-to-date information in the field, with special attention given to electronic research programs such as WestlawNext, LexisNexis interface, Shepard’s online, and Westlaw’s KeyCite.
