While many fans remember The Lone Ranger, Ace Drummond and others, fewer focus on the facts that serials had their roots in silent film and that many foreign studios also produced serials, though few made it to the United States.

The 471 serials and 100 series (continuing productions without the cliffhanger endings) from the United States and 136 serials and 37 series from other countries are included in this comprehensive reference work. Each entry includes title, country of origin, year, studio, number of episodes, running time or number of reels, episode titles, cast, production credits, and a plot synopsis.
