This fourth edition expands the treatment of online research using WestlawNext and Lexis Advance, as well as free or low-cost providers and governmental websites. The text emphasizes sources of Florida state law and includes references to analogous federal sources, making it a compact reference for planning both state and federal law research. The chapters have been reorganized so that the process of legal research is covered at the beginning of the book, along with concrete suggestions for organizing research in different media. A chapter on looseleaf services has been replaced with a new chapter covering a variety of practice tools, including blogs. The text also provides an overview of current citation rules for Florida sources. A new co-author, Jennifer LaVia, teaches at Florida State University College of Law, bringing insights to the needs of current Florida law students. This book is part of the Legal Research Series, edited by Suzanne E. Rowe, Director of Legal Research and Writing, University of Oregon School of Law.
