This is a growing list of documentaries on modern world history. Note that most streaming licenses are usually for one or three years, which means that links can fail. Also be aware that these lists are of films that have been available, which does not mean that they currently are.
If you'd like assistance finding a documentary on specific topics or would like a title included, write your librarian Dr. Bee Lehman.
