These are all to be found in a single manuscript in the Manx National Heritage Library, M 2042A, fos. lr-14r. This MS formerly belonged to John Selden, and is almost certainly the text used by Sir William Dugdale in his Monasticon Anglicanum (6 vols., London 1665), I, 711-17; 2nd edn. (8 vols., London, 1817- 30), V, 253-6. The texts are also found in Bodleian Library, Oxford, MS Add. C 64, fos. 55r-57r, 58r-66v, 113r-116r, which seems to have been the basis for David Wilkins’ edition in the Concilia Magnae Britanniae et Hiberniae (4 vols., London, 1737). A third MS containing them is in Gonville and Caius College, Cambridge, MS 793 (P 28), pp. 53-79. However, it appears that both the Oxford and the Cambridge manuscripts depend (independently of each other) on the first, and are therefore valuable mainly for occasional conjectural emendations.
