Notes made in the seventeenth century by the antiquary John Selden, found among Selden's papers in the library of Lincoln's Inn, London, provide useful information on texts preserved in a twelfth-century charter roll of St Paul's Cathedral, now lost. See Simon Keynes, 'A Charter of King Edward the Elder for Islington', Historical Research 66 (1993), pp. 303-16.,
The 'new' material from Selden's notes, with a reconstruction of the twelfth-century roll, is published in Charters of St Paul's, London, ed. Susan Kelly, Anglo-Saxon Charters 10 (Oxford, 2004).
