 Although exhibitions of some of the materials are periodically held, access to the full collection of manuscripts held in Corpus Christi College is limited to scholars.The public are able to see some of the treasures of the library at open days, notably during the annual 'Open Cambridge' event, or, since the addition of the vault and new learning facilities on the ground floor has freed up room in the original library, on private tours.The collection was begun in 1376, shortly after the College's founding, and much improved by a bequest from Matthew Parker in 1574, the college's Master between 1544 and 1553.
