I know there’s that great, sprawling historical novel that a lot of us have dying to get out on paper, lol and if you don’t want to get called out by a historian over inaccuracies, Writers Dreamtools has a very comprehensive list of major historical events that have occurred every decade since 1650.
I also wanted to mention the site because I’ve always been a sucker for notebook/page layout type websites and wanted to bookmark it someplace. 🙂
