I've done a bit of research in the course of writing my works in progress. They're "historical" fantasy, stories set in my versions of colonial and civil war era America. I slogged through books on the French and Indian War, women in the colonial era, collections of letters by settlers in Minnesota, and more websites than I can count. Hopefully the facts I've collected will make my worlds deep and stable enough to hold my stories.
Are you a researcher or do you create your worlds out of whole brain-cloth? How do you organize your research or inspirations?
