The 2011 Supplement to Ribstein & Lipshaw, Unincorporated Business Entities (4th Edition) is now available in Word and Pdf. It will be posted on the Lexis website in the next couple of weeks.
If you want to teach the law of business associations as many of your students will actually be practicing it — the cutting edge world where contracts and transactional planning matter — and if you want a deep approach to this subject matter rather than just a couple-week add-on to the same old corporations course, then this book is for you.
On the other hand, if you want the latest version of the 19th century “agency and partnership” course, or to continue teaching your grandparents’ corporate law course, with the same old soporific cases (or, maybe, “hip” new cases containing the same old soporific law), then of course you can do that, too, but not with this book.
