One of the big perks of being a writer is I get to indulge my addiction to history and cultures. I've always sworn that if I hadn't studied the arts, I would have been a cultural anthropologist. History is about stories, after all - of people, of places, of the things that were cherished, or left behind, or passed down. Fascinating stuff.
Anyway, during my research travels across the web, I'm come across some great collections and archive sites. You can fall down a rabbit hole into each one of these and not connect with reality for several hours.
