To mark Britten's centenary, the British Library has also digitised all of its Britten manuscripts, which are now available online at http://www.bl.uk/manuscripts in a special arrangement with the rights holders. Many of the manuscripts are on permanent loan to the Britten-Pears Library in Aldeburgh, under the terms of Britten's will, so the library hopes the digital facsimiles will make it easy for researchers and others with an interest in Britten to study his manuscripts wherever they are.
In addition, a number of talks and performances have been arranged. For further details, please see http://www.bl.uk/britten
