Joseph Johnson (1738-1809) was arguably the foremost bookseller of the late 18th century in England, publishing Joseph Priestley, William Cowper, Anna Laetitia Barbauld, Mary Wollstonecroft, Wordsworth and Coleridge, among others, and his output closely linked to the turbulent events of his age. This book seeks to reassess the reputation of a man unfairly condemned in his own time as a dangerously 'radical' publisher and how far the works he published tended to promote the case for religious and political reform.
