Codices Latini Antiquiores ("The More Ancient Latin Manuscripts"), generally abbreviated CLA, is a catalogue of all surviving manuscripts in Latin (whether codices or scrolls) written before the 9th century. The complete title of the work is Codices Latini Antiquiores: A Paleographical Guide to Latin Manuscripts Prior to the Ninth Century. Elias Avery Lowe founded the project in 1929 and directed it himself until his death in 1969.
