The Joseph Johnson Letterbook is the first scholarly edition of the correspondence of the influential publisher Joseph Johnson (1738-1809). Best known today for his work with politically progressive figures such as Mary Wollstonecraft and Joseph Priestley, over the course of his career Johnson was involved in the publication of thousands of works on a breathtaking range of subjects, from travel narratives to scientific writing to children’s books. Johnson was also something of an impresario, and given his active involvement in shaping the books he published, he appears in the longue duree of eighteenth- and nineteenth-century British print culture as a gateway figure in the slow transition from patronage to marketplace. The Joseph Johnson Letterbook brings into print for the first time over two hundred of Johnson’s letters from archives around the world.
