Critical to the study of every aspect of early America, Early American Imprints contains virtually every known book, pamphlet and broadside published in America between 1640 and the first two decades of the 19th century—more than 75,000 printed items in all. This remarkably comprehensive collection is based on renowned bibliographies by Charles Evans and Roger Bristol and by Ralph R. Shaw and Richard H. Shoemaker. It has recently been expanded with newly discovered items from the holdings of the Library Company of Philadelphia and the American Antiquarian Society. Each imprint is expertly indexed and may be browsed by genre, subjects, author, history of printing, place of publication, and language. Subjects include economics and trade; government; health; historic events; labor; languages; law and crime; literature; military; peoples; philosophy; politics; religion; science and technology; society, manners and customs; and theology.
