Book Review: Blue Marble Premises and Principles
Summary: Michael Quinn Patton’s Blue Marble Evaluation is a forward-looking, path-breaking, and timely contribution to evaluation theory and practice. The title of the book evokes the Blue Marble shot—a photograph of the whole earth taken by the Apollo 17 astronauts in 1972. The preface of the book displays the first image of our lonely planet captured from space in 1968 (Earthrise).
