Manuscript produced in Scotland, containing the older chartulary of the Bishopric of Moray. The manuscript is a composite register and contains material written at different times in various hands, from the latter half of the 13th century down to the late 16th century. The material covers the 12th to the 16th centuries.

The bulk of the manuscript, folios 1-114, was possibly brought together in the late 14th century after the destruction of the Cathedral. There are later additions and interpolations throughout the manuscript.

The contents are as follows:

Shelfmark and ownership inscriptions. Folios i-ii.

A letter to William Dickson from Alexander Rose dated 1 November 1922, detailing a fragment of an index of a Chartulary of Moray in Montrose Museum. Folios iii-v.

Title and shelfmark inscriptions. Folio vi.

The register of the Dean and Chapter, containing the foundations and constitutions of the Chapter and the progressive increase of the canonries and prebends of the Cathedral. The index of its contents, 'Rubrica Cartarum in hoc libro', has been mistakenly placed at folios 65r-66v. This part of the manuscript is written in a uniform hand of the late 13th century, with a few later insertions towards the end. Folios 1r-34v.

A record formed apparently for the use of the Bishops, containing much the same material as the previous section. It is likely that this section formed an independent register before being incorporated with the rest of the material. It is lacking the Canons and Constitutions, but contains a larger number of charters which are concerned with episcopal privileges and property. Many of the entries in these two sections have been copied from the same originals. If a charter occurs in this section which was not in the previous a marginal note, written later than 1400, states that 'Ista non scribitur in libro Decani'. This part of the manuscript is also in a hand of the late 13th century, with a few later insertions. Folios 35r-43r.

From folio 43v until folio 114v the register of the Bishopric continues. This section contains a variety of insertions and additions of royal, papal and episcopal charters, as well as other documents relating to the church and see. These do not appear to have been arranged in any discernible order. On folios 68r-69r are lists of taxations and procurations of the churches of the diocese, and a list of utensils on folio 69r. There follows a list of the first 14 Bishops of the See on folio 69v.

Charters of the 15th century in favour of the Bishopric, entered contemporaneously. Folios 115r-117v.

Charters of alienation by Bishop Patrick Hepburn, 1538-73. Folios 118r-169v.

An illegible inscription and another dated 4 July 1580. Folio 170r. The verso is blank.

An inscription for George, Bishop of Moray, dated 1573. Folio 171r. On the verso is possibly a notarial instrument of the 15th century, obliterated in places.

Folios 1r-31v are decorated with red initials and rubrics in red. Guide letters are visible in the margins. The work here is written in a single column. The rest of the manuscript is not decorated. Folios 35r-43r are written in double columns with spaces left for rubrics.

Throughout the manuscript are extensive marginalia, nota and maniculae, both scribal and later. Representations of maniculae and grotesques are also present.

There are two sets of early foliations, one in Arabic and the other in Roman numerals. The foliation in Roman numerals skips from 76 to 79 but the record is continuous. These foliations have since been superseded by a modern Library foliation.

There is evidence of contemporary and modern repairs to the vellum throughout. Many leaves of the manuscript are damaged due to stains from dirt and damp. Several of the leaves have been treated with a gallotanic solution which has rendered some text illegible.
