Which are the best buildings to see medieval illuminated mcripts in, in Paris, France?

I ume there are some in the Bibliotheque Nacionale there, but I don't know for sure and I also don't know how many, or which ones, are on display. Does anyone know? I'm particularly interested in Gothic illuminated mcripts. Where else should I go in Paris to see such mcripts? I've been to Chantilly (and, of course, though wonderful, it is not in Paris.) Help, please. Merci.
