Since each strip comprises a horizontal section across both sides of a bifolium, it contains music from the verso and recto of a leaf.
The latter will provide both a verso (including what survives) and a reconstructed recto containing the missing portions of this composition.
An indication is always given of whether a mark should be viewed from the recto or the verso of a leaf.
Each sheet contains two folios, recto and verso, but blank folios have been omitted from the totals.
The recto originally contained rulings for staves 1 and 3-7, out of the twelve possible on the leaf.
The verso side of the fragment shows more deterioration than the recto side.
There are fifty-five pages (including the separate title page occupying the opening recto side), all numbered by the library itself.
This recto evidently was left as a cover page, and its worn condition would indicate that it functioned in that capacity for some time.
