The Liber feudorum Ceritaniae is, as its Latin title indicates, a book registering the fiefs (feudi) within the counties of Cerdagne (Ceritania), Roussillon and Conflent, and the feudal obligations of the count and his vassals. It is preserved in the Arxiu de la Corona d'Aragó and consists of 272 charters in 379 folios with 32 colourful miniatures on a golden background. It was probably originally copied from a part of the Liber feudorum maior (LFM), which is several decades older. It contains all the documents pertaining to Cerdagne and Roussillon found in the LFM and in exactly the same order, as well as six documents more. Most of the charters in it cover the years 1172–6.

A cartulary or chartulary, also called pancarta or codex diplomaticus, is a medieval manuscript volume or roll (rotulus) containing transcriptions of original documents relating to the foundation, privileges, and legal rights of ecclesiastical establishments, municipal corporations, industrial associations, institutions of learning, or families. The term is sometimes also applied to collections of original documents bound in one volume or attached to one another so as to form a roll, as well as to custodians of such collections.
