This volume is a welcome addition to the growing number of new editions of Anglo-Saxon charters. It brings together the sixty-one surviving pre-Conquest charters from the Glastonbury archive, along with important ancillary material: summaries of the entries in the (lost) Liber terrarum and the Index chartularium; an edition of the pre-Conquest entries in the list of Glastonbury muniments in Longleat ms 39A; an edition of an authentic papal letter and a forged papal privilege relating to the abbey; and an edition of the so-called Ineswytrin charter. Glastonbury was the wealthiest pre-Conquest monastery and its muniments are of particular historical interest, not least for the light that they throw on the monastic reform movement of the mid-tenth century. Glastonbury's archive also presents the historian with particularly interesting source-critical issues: only one charter from the archive survives in original format and the witness-lists of the remaining documents have all been abbreviated (sometimes very heavily), making it difficult to judge their authenticity. Still, a wealth of ancillary evidence survives to assist the historian, which Susan Kelly deploys to good effect: various medieval and early modern catalogues and indexes shed light on the archive and its history, whilst William of Malmesbury's writings provide an important further angle from which to approach the material. In general, Kelly rises to the editorial challenge set for her with aplomb: she provides a detailed introduction to the abbey's history and muniments and her editions and discussions of individual charters are of a consistently high standard. There is some overlap at points, with arguments often appearing in the introduction as well as in discussions of individual documents, but this is to be welcomed, since not every reader will wish to consult all 624 pages of the volume. On specific issues of diplomatic, there are naturally points at which opinions will divide (for example, the present reviewer is not entirely convinced by Kelly's case for the authenticity of S 626 and 724), but Kelly always makes good arguments and is more than happy to admit to a degree of uncertainty when appropriate. There are, however, points at which her editorial decisions may be queried. In particular, the decision to print S 473 (one of the so-called ‘alliterative’ charters) in verse (‘in order to display its literary qualities more clearly’: p. 382) seems unfortunate, since this creates the misleading impression that the single sheet original would have looked different from those of the other charters in the volume (which, it should be noted, includes one other ‘alliterative’ charter, in this case printed in prose format). The volume also shows signs of hasty production: the prose of the introduction often seems to lack a sense of direction (see, in particular, the discussion of the Liber terrarum at pp. 87–96, 101–3); a large number of typos are present in the text (e.g. p. 88: ‘the contents list does not contain a reference to a charter of Æthelred in favour of Abbot Beorhtred,which’; p. 138: ‘The argument are’; p. 383: ‘in Eadnund's reign:,’; p. 502: ‘According to Ælfheah s will’); and the margins at p. 554 are incorrectly set. How much of this is to be laid at the editor's feet and how much at the Press's is a good question, but either way it is unfortunate that a volume with this price-tag should contain so many errors. Still, one should not be too negative: this edition is an important milestone in the on-going process of re-editing the charters of the Anglo-Saxon period and Susan Kelly is to be congratulated for throwing much new light on Glastonbury and its environs in the early Middle Ages.
