1⁴( -1) 2³ 3² 4-13⁴, 14⁴( -2); folios 44, 47, 60, 65, 77, and 80 are tipped in. Quires are misbound, as is evident from the catchwords, lower center of last verso (some trimmed away). Original order is uncertain. Several quires appear to be missing: after quire 1, before quire 2, before quire 6, before and after quire 10, and after quire 12. The beginning of the manuscript is missing and a label has been removed from the current first leaf. Two sequences can be reconstructed: quires 2, 3, 4, 5, 11, 12 (f. 8-33, 74-89) and quires 6, 7, 8, 9, 13, 14 (f. 34-65, 90-103). The documents are not in chronological or alphabetical order. The first digits of the 16th-century foliation have been erased, leaving repeating arabic numerals, 0-9, upper right recto (i.e. 0,1,2,3,4,5,6,7,8,9,0,1,2,3, ...); modern foliation in pencil, lower right recto.
Disbound; sewn, with paste on spine, but no binding; sewing, probably not original, is very delicate; many quires pulling loose, and several are practically detached from the rest of the codex.
Written in Aragon (Spain) in the second half of the 13th-century; the documents themselves are earlier in date than the present copies; the latest dated document is dated January 9, 1256 (f. 18r).
