Abstract: "The ninth edition preserves the authors' tradition of providing a comprehensive overview of agency, partnership, and corporation law. It also continues to emphasize six basic editorial principles: Be lean but not mean, cases edited ruthlessly to produce a readable and concise result. Facts matter, so they are included in all their potential ambiguity. Bring a planner's perspective to the table through extensive use of transactionally-oriented problems. It's a casebook not a treatise. No long, stultifying textual passages. Provide the cases and let the individual teacher use them as he or she sees fit. Try to find cases that are fun to teach. Great facts or a clever analysis are always given first priority in case selection. Provide a teachers' manual that goes into great depth, with analysis of every case and, whenever applicable, offering the disparate views of each author." --Publisher Supplements (1993, 1998, 1999, 2001, 2005, 2008, 2010, and 2014); Teachers' Manual with Supplements (1991, 1993, 1998, 1999, and 2001); and annual Statutory Supplement.
