Give Smart: Philanthropy That Gets Results by Thomas J. Tierney and Joel L. Fleishman

I have the feeling that this book is aimed at people who have a lot more money to give away than I will ever hope to make. It's mostly a set of questions that you can ask yourself in order to make your philanthropy as effective as it can be, in addition to a series of stories (sometimes cautionary) and case studies about philanthropists and their works. The book is very invested in the idea that philanthropists are only accountable to themselves for excellence (which makes it very hard to achieve) and that it is worth paying good overhead to get the right kind of people so that the philanthropy works (as opposed to bad overhead for fancy cars or whatever).
