The Ninth Edition of Securities Regulation: Cases and Materials brings onboard two new co-authors--Ann Lipton and William Sjostrom--to a casebook that has long set the standard for providing students with an in-depth, sophisticated, practical look at contemporary securities law. As it has since its first edition, Securities Regulation: Cases and Materials contains a very teachable mix of problems, cases, and textual material, encouraging students to build their knowledge base by being active problem-solvers. Always forward-thinking, stressing current developments and controversies, the book is also highly modular, so that professors can easily pick and choose how to structure their courses without being locked into any given progression.
