Definition | Mathematical data associated with cartographic material, including a statement of scale, statement of projection and/or a statement of bounding coordinates. The coordinates can represent a bounding rectangle, the outline of the area covered, and/or the outline of a statement of bounding coordinates. For celestial charts, it may also contain a statement of zone, declination data, and/or right ascension data, and/or equinox. Enter a corresponding 034 field for each 255 field. Use field 500 for additional information about projection, coordinates, zone, and equinox. Use separate 255 fields for a multipart item with two different scales or a single item with components having two different scales. If a multipart item has three or more different scales, use one 255 field and enter Scales differ. See Cartographic Materials, Map Cataloging Manual and the Cataloging Service Bulletin for more information. If you are entering a scale note for pre-AACR2 cataloging, use field 507. |

Printing | Field 255 prints in the title paragraph following the title ( field 245) or edition statement ( field 250). All subfields of field 255 print in the order entered, exactly as entered, including punctuation. If you use multiple 255 fields, only the first two print. The print program supplies a space-dash-space ( -- ) between information in field 255 and the fields that precede and follow it.
