A new resource for Grosseteste, and wider medieval, manuscript research, is now available on the Ordered Universe website. It comprises a list of all known manuscripts of Grosseteste’s scientific, theological and philosophical opuscula. Compiled by Professor Neil Lewis (Georgetown University), the list is designed to be iterative: if you come across new sources of information, conformation or query, please alert Neil to them, at the address indicated on the page. We hope that the list will prove useful in teasing together the complex history of the manuscript transmission and, by extension, the afterlife of Grosseteste’s ideas. Considerable thanks are due to Neil for his work on this resource.
