How the Paperback Novel Changed Popular Literature

With its quality fare and fine design, Penguin revolutionized paperback publishing, but these were not the first soft-cover books. The Venetian printer and publisher Aldus Manutius had tried unsuccessfully to publish some in the 16th century, and dime novels, or “penny dreadfuls” –lurid romances published in double columns and considered trashy by the respectable houses, were sold in Britain before the Penguins. Until Penguin, quality books, and books whose ink did not stain one's hands, were available only in hardcover. http://www.smithsonianmag.com/arts-culture/How-the-Paperback-Novel-Changed-Popular-Literature.html
