During the eighteenth century, there were several attempts to describe a "women's literary tradition." This table compares six eighteenth-century collections of notable women: George Ballard's Memoirs of several ladies of Great Britain (1752), John Duncombe's The Feminead (1754), the Biographium Faemineum (Anon., 1766), Mary Scott's The Female Advocate (1775), Richard Polwhele's The Unsex'd Females (1798), and Mary Hay's Female Biography (1803).
