Harold Lloyd, born in 1893, became one of the greatest comic actors in America. This is a compendium of all things Lloyd, with entries on noteworthy persons, recurring themes, crucial elements of Lloyd's life (birth, education, marriage, family, hobbies, death, etc.), his prime co-stars and co-workers, the films that made him a legend (201 of them), and numerous other topics covering every facet of the man and the actor, all fully cross-referenced and accompanied by a vast collection of images and advertisements.

An Appendix A lists the Lloyd shorts in the order produced, with the Production Code assigned by the Rolin Film Company officials. Appendix B is a proper filmography, listing each Lloyd film from 1913 to 1966 in chronological order.
