Description/Instructions:
Field 255 contains mathematical data associated with map material, including a statement of scale, statement of projection, and/or a statement of coordinates. For celestial charts, the field may contain a statement of scale, the zone, declination, and/or right ascension data, and/or equinox. The mathematical data in this field is also recorded in coded form in field 034 (Coded Cartographic Mathematical Data) to facilitate retrieval.
Field 255 is used as specified by AACR2 rules. This field is repeatable due to specifications in Cartographic Materials: A Manual of Interpretation for AACR2, prepared by the Anglo-American Cataloguing Committee for Cartographic Materials. Example:
