Up next in my resource series (last time I did it on Japan), is the 1920s. This wonderful era is known for flappers and loose morals, and also sits in between WWI and WWII. My book, Those Crazy Years, is an alternative history of the 1920s, set in a version of New York City and Chicago.

This is not a nearly complete list of resources I'd like to give you, but for the moment, this is what I've been able to come up with. If you have any other resources (no matter how obscure), please comment below with what they are (they don't have to have links online, as long as you give us enough information to be able to reasonably find them ourselves, that's fine). Also, sadly, some of my favorite resources are no longer existing or for some reason I can't access them.

In any case, I'd continue to update this as I go. But remember that many more resources are simply found through Google and its many sub-resources (like Google Books and Google Scholar). Remember that if you're writing anything other than fiction, it's always a good idea to back up anything in particular you find with at least two other sources unless its something that's common knowledge. Also, its always a good idea to let other people know where you get your information from (citations, people!).
