A friend has just attended a conference at Harvard, relating to the Houghton Library's recent acquisition of two important manuscript sources of Ambrosian chant, the body of music in the use of Milan before the Gregorian reform. These manuscripts go with a fragment the library has owned for a while, recently identified as Ambrosian chant. Not only are these books in Cambridge, the library has made high-quality digital scans of each page, recto and verso, and put them on the Internet. Click on the images below to get your virtual hands on some medieval vellum. No library card or white gloves required.
