The cover of this document is composed of two, partially overlapping stacks of five layers of paper pasted together, with a blank parchment wrapper. Only the inner fragment is visible.

The bifolium used as back cover and flap of the manuscript contains chapters 4-6 and 20-21 of Sallustius' De coniuratione Catilinae; the bifolium used for the front cover and also visible in the inner margin of the back cover contains chapters 6-7 and 20. The two fragments were thus consecutive bifolia of the same quire.
