I have been compiling a list of d100/RuneQuest derived game settings and supplements for medieval and late antiquity play; specifically books that contain a lot of core information (society, religion, history). Due to the latter I don't have many adventures listed, nor do I list all Pendragon products.
The list, to be updated whenever I discover more, is on my d100 blog here:

I would welcome any further suggestions.
