At the beginning of the 20th century, the history of Latin script was insufficiently known and based only on partial analyses. Historians strongly felt a need for a complete international catalogue of early manuscripts, to evaluate the differences in importance between the various cultural centres of book production, the transmission of ancient culture, and the creation of new
ways of writing.
CLA covers only literary works; this includes legal texts but not documentary texts such as charters. It has 11 volumes, organized according to the current location of the manuscripts; these were followed by a supplement in 1971 and two sets of addenda published in 1985 and 1992.
Paleography is the foundational principle of the project: every entry is accompanied by a photograph of the manuscript in black and white, at a 1:1 scale, along with a description of its contents, its state of preservation, the kind of writing used, and the possible date and geographical origin.
Similar works Two similar projects have appeared: the first one for documentary texts from antiquity and the
Early Middle Ages, under the title
Chartae Latinae Antiquiores (
ChLA). The second, under the title
Manuscrits datés, was directed under the auspices of the
Comité international de paléographie latine. Unlike CLA and ChLA, it covers the entire medieval period, but is confined to manuscripts bearing a specific date or datable within a narrow period. Other editorial projects have a more limited scope: • Gamber, Klaus (1919–1989),
Codices liturgici latini antiquiores, Freiburg, Universitätsverlag, 1963; 2nd ed. 1968; suppl. and index, 1988.
Reprint of 1988 CLA was reprinted in 1988, though in a reduced format in comparison to the original. ==Author and collaborators==
