I love research. When I wrote my undergraduate honors thesis examining the process of writing historical fiction, I spent far more time researching the history than writing the fiction. To that end, I have added a secondary page (in the upper right corner of the site, if you’re accessing it via a computer) of resources devoted to medieval research.
I’ll continue to add to the list, but for now, there are several links to comprehensive sites, and a couple of links to cooking sites.
If your writing requires you to do medieval research, I’m sure one of these links will be a good place to start!
