Although Augustan literature played an important role in Crabbe's life and poetical career, his body of work is unique and difficult to classify. His best works are an original achievement in a new realistic poetical form. The major factor in Crabbe's evolving from the Augustan influence to his use of realistic narrative was the changing readership of the late 18th–early 19th century. In the mid-18th century, literature was confined to the aristocratic and highly educated class; with the rise of the middle class at the turn of the 19th century, which came with a growing number of provincial papers, the heightening in production of books in weekly instalments, and the establishment of circulating libraries, the need for literature was spread throughout the middle class.
