The Walters Art Museum in Baltimore has published scanned images and descriptions of many of their manuscripts under a Creative Commons Non-Commercial License (http://www.thedigitalwalters.org/Data/WaltersManuscripts/). I have taken the manuscript images and published them using the Internet Archive BookReader. With substantial help from Doug Emery I’ve modified the BookReader to take information directly from the TEI-encoded manuscript descriptions provided by the Walters, and also to configure right-to-left navigation for non-Western manuscripts.
Please note that the BookReaders pull large image files from a distant server, so it may take a minute or so for images to populate fully.
This is the index for now; eventually I will be creating a more extensive catalog, with more descriptive metadata. Check the blog for updates as things progress.
