Newton Papers"Cambridge University Library holds the largest and most important collection of the scientific works of Isaac Newton (1642-1727). They range from his early papers and College notebooks through to the ground-breaking Waste Book and his own annotated copy of the first edition of the Principia. These manuscripts along with those held at Trinity College Cambridge, King’s College Cambridge, the Fitzwilliam Museum, the Royal Society and the National Library of Israel have been added to the Unesco Memory of the World Register. As well as University Library material, our collection includes two important items from The Royal Society's collections - a manuscript copy of the Principia and a collection of Newton's correspondence."
