The preface by Ælfric occurs in complete form in two manuscripts and in part in a third. Oxford, Bodleian Library, Laud Miscellany 509 (s. xi2) contains the preface (fols. 1–3, headed with the words Incipit prefatio genesis anglice), together with the Old English Hexateuch (fols. 3–107) and Ælfric's selections from Judges (fols. 108–15). Cambridge, University Library, Ii. 1. 33 (s. xii2) has the preface, without tide, followed by Ælfric's partial translation of Genesis (fols. 2–24). London, British Library, Cotton Claudius B. iv (St Augustine's, Canterbury, s. xi1), having lost its first leaf, now preserves only the second half of the preface followed by an illustrated text of the Old English Hexateuch, but a sixteenth-century transcript by Robert Talbot, Cambridge, Corpus Christi College 379, preserves some of its missing text, along with the same tide as Laud 509. Both Laud 509 and Claudius B. iv give slightly different compilations of the translations by Ælfric with the more extensive work of the anonymous scriptural translator (or translators). The differing rubrics and contents of the manuscripts affect the way we read the preface that they share: the Cambridge manuscript presents it as a preface to half of Genesis only, Laud 509 and the transcript label it a preface at least to the whole of Genesis. If, however, the incipit is scribal, it could be taken as a prologue to the Hexateuch. Was the preface, then, intended by Ælfric to introduce just the first half of Genesis, or a larger work? Sisam is of the first view: ‘no preface to the Pentateuch (or Hexateuch) survives, and evidendy the compiler of the extant Old English version did not know of one, since he used Ælfric's inappropriate English preface to the first part of Genesis.’
