As part of an application submitted by the University of California, Riverside Libraries to the NEH, the Columbia University Libraries/Information Services is proposing to help make available uncataloged pre-1600 manuscript leaves through a database of images and metadata. The images are of detached pages (single leaves) produced on the continent of Europe and currently in holdings of North American collections.

The proposed Single Leaf Registry database will be designed for compatibility and data sharing with the Digital Scriptorium.
