This book is pretty good and reasonably up to date: https://www.amazon.com/Entrepreneurs-Guide-Business-Law-4th/...

We used an older edition as a textbook in a Venture Capital seminar back when I was in law school.

The Entrepreneur's Guide to Business Law: http://www.amazon.com/Entrepreneurs-Guide-Business-Law/dp/05...
