This work examines in detail the length of baseball games at all levels, in all countries, and all eras. If a game lasted 20 or more innings, or five or more hours, or ended after 1 ., you will find it here. This effort represents 46 years of work, begun in 1963. I am very thankful for the tremendous assistance along the way by fellow baseball researchers, many of whom are members of the Society for American Baseball Research (SABR). Those most helpful have included David Black, Patrick Gallagher, Karl Knickrehm, Tim Copeland, Richard Musterer, John Thorn, Miles Wolff, Lloyd Johnson, Tom Kayser, Branch Rickey, Miwako Atarashi, David Skinner, Yuyo Ruiz, Yogo Suzuki, Jon Clark,.
