This list is "an educational resource that offers guidance and encouragement as students seek to find points of orientation within the vast history of film and video." It is not a list of the best films of all time. Rather, it reflects a variety of criteria.

100 Documentary Films is the first book to offer concise and authoritative individual critical commentaries on some of the key documentary films - from the Lumière brothers and the beginnings of cinema through to recent films such as Bowling for Columbine and When the Levees Broke - and is global in perspective. Many different types of documentary are discussed, as well as films by major documentary directors, including Robert Flaherty, Humphrey Jennings, Jean Rouch, Dziga Vertov, Errol Morris, Nick Broomfield and Michael Moore. Each entry provides concise critical analysis, while frequent cross reference to other films featured helps to place films in their historical and aesthetic contexts.
