Eric Friedman, a long-time GiveWell supporter, recently authored a book, Reinventing Philanthropy, about effective charitable giving. I read an early draft of the book in the spring of 2012, and especially appreciated Mr. Friedman’s focus on “issue-agnostic giving,” a value we share. For donors looking for more material that’s aligned with our perspective on charitable giving, we recommend checking out Mr. Friedman’s book.
