This volume is modelled on The Durham Liber Vitae, edited by David Rollason and Lynda Rollason in three volumess (London: The British Library, 2007), and generally follows its organisation and conventions. Following this model, at the core of the volume is the edition of the Thorney Liber vitae which, with the twelfth-century relic-list (fol. 11v), and the fifteenth-century abbots’ list (fol. 11r), is an addition to the tenth-century Gospel-book, London, BL, Additional MS 40,000. In imitation of the Monumenta Germaniae Historica, Necrologia series, the edition is organised in stints. A stint is defined here as a block of text entered by a single scribe in a single campaign and on a single page. This means that, even where a scribe has continued in the same campaign on to another page, his work on that page is treated as a new stint. Each page of the liber vitae has been edited as a series of stints, each of which has a number relating it to the page on which it appears and generally to the sequence in which it was entered on the page relative to the other stints, assuming that the main body of the page was completed first and the margins subsequently filled. Thus 10v6 refers to the sixth stint to have been entered on folio 10v. Each stint as it appears in the edition is dated palaeographically using a system of letters and Roman numbers. Thus the number s. xii1/4 following stint 10v6 means that the stint has been dated on palaeographical grounds to the period c. 1100–25 (for a definition of all the palaeographical datings used, see below, p. 79). Where the Prosopographical Commentary provides very clear evidence that an identification of a name within a stint permits a more precise dating of it, a further date has been given in Arabic numerals following the palaeographical dating. Thus ‘s. xiiex (1176–93)’ following stint 1v3 means that one of the identifications in the stint restricts it to the date-range set out in Arabic numerals. In this case 1v3(5), a man called Richard, is additionally described as the brother of Abbot Solomon (Ricardus frater abbatis Salomonis) so the stint was presumably written during Solomon's abbacy of Thorney, that is 1176–93.
