This work was made possible in part through the generosity of a number of individuals and foundations. Their thoughtful support will help ensure that it is affordable to schools, libraries, and other not-for-profit institutions.

The Lucius N. Littauer Foundation made a leadership gift before a word of this book had been written, a gift that set this project on its way. Hugo Barreca, The Marian B. and Jacob K. Javits Foundation, Mr. and Mrs. Peter Malkin, David P. Solomon, and an anonymous donor helped ensure that it never lost momentum. We are deeply grateful.
