The dime novel is a form of late 19th-century and early 20th-century American popular fiction issued in series of inexpensive paperbound editions. The term dime novel has been used as a catchall term for several different but related forms, referring to story papers, five- and ten-cent weeklies, "thick book" reprints, and sometimes early pulp magazines. Dime novels are similar in form and content to British penny dreadfuls and story papers, which were produced at the same time.
The term was used as a title as late as 1940, in the short-lived pulp magazine Western Dime Novels. In the modern age, the term dime novel has been used to refer to quickly written, lurid potboilers, usually as a pejorative to describe a sensationalized but superficial literary work.
