Gospel of Barnabas
Among the collection are many rare items such as one of the two extant copies of the "Gospel of Barnabas", and an annotated first edition of "Philosophiae Naturalis Principia Mathematica" by Sir Isaac Newton. In 2017, a member of staff discovered an original Giorgione sketch in Rare Books and Special Collections with a definitive date and cause of death for Giorgione, information that had been lost for over 500 years in a 1497 edition of Dante Alighieri's Divine Comedy.
