This catalog provides "a simple means to discover medieval manuscripts available on the web." Searchable, or browse by location, shelfmark, title, author, language. The site notes that "[a]s the project develops, a richer body of information for each manuscript, and the texts in these codices, will be provided, where available." From the Center for Medieval and Renaissance Studies, University of California, Los Angeles.
