A number of different numbering schemes are used. The most widespread is CIIC, after R. A. S. Macalister ("Corpus Inscriptionum Insularum Celticarum", Latin for "corpus of Insular Celtic inscriptions"). This covers the inscriptions known by the 1940s. Another numbering scheme is that of the Celtic Inscribed Stones Project, CISP, based on the location of the stones; for example CIIC 1 = CISP INCHA/1. Macalister's (1945) numbers run from 1 to 507, including also Latin and Runic inscriptions, with three additional added in 1949. Ziegler lists 344 Gaelic ogham inscriptions known to Macalister (Ireland and Isle of Man), and seven additional inscriptions discovered later.
