Manuscripts, sources and themes

In this rubric, except some websites containing important corpora of sources (translated or not), the selection has been deliberately restricted to sites which share a desire to make available medieval sources - textual or visual - preferably with a developed critical apparatus.
Some are centred on a manuscript (Aberdeen project) or a work (of Robert Grosseteste for instance), others on an individual (Richard III) or a movement (lollard heresy) ; some, finally, want to present a large corpus and are often in construction (corpus of roman sculpture for instance).
