There are several other important libraries in the city. Among them is the Morgan Library, originally the private library of J. P. Morgan and made a public institution by his son, John Pierpont Morgan. It is now a research library with an important collection, including material from ancient Egypt, Émile Zola, William Blake's original drawings for his edition of the "Book of Job"; a Percy Bysshe Shelley notebook; originals of poems by Robert Burns; a Charles Dickens manuscript of "A Christmas Carol"; 30 shelves of Bibles; a journal by Henry David Thoreau; Mozart's Haffner Symphony in D Major; and manuscripts for George Sand, William Makepeace Thackeray, Lord Byron, Charlotte Brontë and nine of Sir Walter Scott's novels, including "Ivanhoe". The library is currently undergoing a significant expansion designed by Renzo Piano.
