Jane Collier was a remarkably innovative and experimental prose-writer of the mid-eighteenth century. She produced one anti-conduct-book, one collaborative novel (written together with Sarah Fielding), a remarkable commonplace-book (only recently discovered), and trenchant literary-critical comments. Other work may have failed to survive: she reached the planning stage, at least, with a tragedy, comedy, farce, her own periodical, a French grammar, and especially periodical essays.
