Inspired by a landmark exhibition mounted by the British Museum in 1963 to celebrate five eventful centuries of the printed word, Nicholas A. Basbanes offers a lively consideration of writings that have made things happen in the world, works that have both nudged the course of history and fired the imagination of countless influential people. In his fifth work to examine a specific aspect of book culture, Basbanes also asks what we can know about such figures as John Milton, Isaac Newton, Samuel Taylor Coleridge, John Adams, Frederick Douglass, Helen Keller, even the notorious Marquis de Sade and Adolf Hitler, by knowing what they have read. He shows how books that many of these people have consulted, in some cases annotated with their marginal notes, can offer tantalizing clues to the evolution of their character and the development of their thought. Taking the concept one step further, Basbanes profiles some of the most articulate readers of our time, David McCullough, Harold Bloom, Helen Vendler, Elaine Pagels, Daniel Aaron and Perri Klass, among them, who discuss such relevant concepts as literary canons, classic works in translation, the timelessness of poetry, the formation of sacred texts, and the power of literature to train physicians, nurture children, and rehabilitate criminal offenders.
