Oxford's Religion in American Life series brought together top-flight scholars in various disciplines to write short, visually interesting, and well-researched books for the YA market. But why hide one's light under a bushel? Recently, Oxford has been repackaging these same books as grown-up paperbacks, moving the illustrations to an eight-page tip-in and bringing the price below $10. Wheaton College historian Mark Noll offers the latest installment in this Religion in America series, entitled The Work We Have to Do: A History of Protestants in America. This huge topic is covered deftly by Noll, who begins with introductory chapters on who Protestants are and where they come from and then traces their fragmented history through four centuries and dozens of denominations. To aid on this score, Noll includes a very helpful appendix that groups the various Protestant denominations into historical families.
