“Johannes Crisostomus de laude Apostoli. 
    In hoc volumine continentur
  Idem de laude Redemptoris. 
  Brutus latine. 
  Nomina Regum Britanniae sicut in ordine successerunt. 
  Nomina Archiepiscoporum Cantuariensis sicut in ordine successerunt. 
  Tabula et questiones Bede de ratione temporum. 
  Tabula ejusdem et expositio super tabulam de lunationibus. 
  Descriptio Britanniae Insulae. 
  Expositio super Merlinum, imperfecta.”

It may perhaps be supposed that this proves too much, as, besides the direct title of the volume, eight “tracts” are here entered, while in the Power of Attorney only two are noticed.  But we would maintain, nevertheless, that it is the identical book, and explain this variation in the description by the circumstance that the library having, in the space of nearly two centuries, been materially enriched, numerous works, consisting in many cases only of a single “quaternion,” were inserted in the volumes already existing.  An examination of the structure of books of this period would confirm this view, and show that their apparent clumsiness is to be explained by the facility it was then the custom to afford for the interpolation or extraction of “sheets,” by a contrivance somewhat resembling that of the present day for temporarily fixing loose papers in a cover, and known as the “patent leaf-holder.”

The second document is a list of certain books, belonging to the monastery of Anglesey, early in the fourteenth century, allotted out to the canons of the house for the purpose of custody, or, perhaps, of study or devotion.
