Illuminated manuscripts, because they are handmade and often contain miniature masterpieces of painting on paper, seem to belong more to the art museum than to a public library.
But a hundred of them are on display in the library's dimly lit D. Samuel and Jeane H. Gottesman Exhibition Hall on the first floor of the stately building at 42nd Street and Fifth Avenue. This is the cream of the library's 300 or so illuminated books. It includes Bibles, prayer books, atlases, scientific texts and romances, dating from the 10th to the 16th centuries.
Sounds like fun ... if you're a NERD!
(...which I think we all are.)
