The Hopalong Cassidy series by Clarence Mulford spans twenty-eight novels published between 1906 and 1941. The books center on the Bar-20 ranch and its crew of cowboys, with Hopalong Cassidy as the main character. The series begins with Bar-20 and follows Cassidy and his companions through decades of frontier adventures.
While Cassidy is the star, several books focus on supporting characters. Johnny Nelson (1920) and Mesquite Jenkins (1928) give other Bar-20 hands their own stories. The series also includes Tex (1922) and Bring Me His Ears (1922), which branch out from the core ranch setting. Mulford kept writing new Cassidy novels for thirty-five years, building one of the longest-running Western series of the early twentieth century.
