Additional Resources for Medieval England". The website proper is about English literature and I stumbled upon the website looking for real-world historical information regarding prices for goods & services.
There are about a bazillion links on this giant link page, and some of them are dead links...BUT...there is usually enough info that a quick web search will get you where you need to go. For example, there is a link to an article on The Black Death which goes to my Alma Mater (Boise State University). The link is dead, but a quick search led me to this page still being hosted on a BSU sub-domain.
