The New York Public Library possesses one of the largest and finest collections of medieval and Renaissance illuminated manuscripts in North America, yet its manuscript holdings are scarcely known to scholars, much less to a wide public audience. Medieval and Renaissance illuminated manuscripts are vehicles of the collective memory of western European culture, and provide a material connection between the scribes, illuminators, and patrons who produced these works and the audiences who view them today. The New York Public Library comprises simultaneously a set of scholarly research collections and a network of community libraries, and its intellectual and cultural range is both global and local, while singularly attuned to New York City. That combination lends to the Library an extraordinary richness. It is special also in being historically a privately managed, nonprofit corporation with a public mission, operating with both private and public financing in a century-old, still evolving private-public partnership. Last year, over 16 million New Yorkers visited the library, and over 25 million used its website. The NYPL Digital Gallery provides free and open access to over 640,000 images digitized from the The New York Public Library's vast collections, including not just photographs but illuminated manuscripts, historical maps, vintage posters, rare prints and more. Digital projects and partnerships at NYPL are managed by the Digital Experience Group, a 21-person team of programmers, designers and producers dedicated to expanding and enhancing all points of computer and Web-mediated interaction with the library's collections, services and staff.
