Long before public libraries, online bookstores that ship directly to our homes, technologies that enable the downloading of publications directly to mobile devices, and social networks supporting virtual book clubs, eighteenth-century book readers relied heavily on literary societies, subscription libraries, and the advice of and selections made by colonial booksellers whose relationships with publishers--most of whom were in Europe-- fostered the exchange of ideas. The books they read varied from fiction to non-fiction titles, and from essays to multi-volume series. They dealt with wide-ranging subjects, including political philosophy. Title pages from such publications of the Enlightenment provide engaging points of entry for student research into the origins of ideas contained in the Declaration of Independence, Constitution, and Bill of Rights. Remind students that a title page is one of the most important parts of a book and that an ideal one includes the book's complete title, the name of the person or organization responsible for its intellectual content, the name of the publisher, the place of publication, and the year of publication. One might also include artwork or illustrations. The three featured in this article come from volumes in the Rare Book and Special Collections Division of the Library of Congress and were featured in the World Treasures of the Library of Congress Exhibition (see www.loc.gov/exhibits/world/worldover. html).
