A computus manuscript, now lost, which appears to have been consulted by Bede in the library of Jarrow and which is thought to have been an influential resource when he wrote his own computistical treatise De temporum ratione. To an extent, its contents can be reconstructed from an 11th-century copy in the so-called Sirmond manuscript and other, related manuscripts, although the precise extent of the material that can be said to derive from the lost compilation is uncertain. Charles W. Jones originally singled out a narrower set of items (items 13-45 in his catalogue description of the Sirmond manuscript), but on later occasions, revised his opinion.

A copy of the Historia Brittonum in the recension ascribed to Gildas.
- s. xiv
A manuscript whose core is a psalter of the mid-9th century, together with preliminary matter, canticles and prayers as well as a calendar, in addition to material which it accrued in the ensuing centuries. Provenance: St. Maximin, Trier. Some features of Celtic Latin interest include the 12th-century insertion of a calendrical obit for Israel the grammarian (obiit Israhel episcopus), who became a monk at St. Maximin's at the end of his life, and the names of Patrick and Brigit that appear in the litany of the saints on f. 112.
