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 coded mathematical data in field 034.

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.

1st Indicator

 Undefined. The 1st indicator position is undefined and contains a blank (blank character ).

2nd Indicator

Subfields
‡a Statement of scale

The entire scale statement including any equivalency statements. Vertical scales or vertical exaggeration statements for relief models or other three-dimensional items are also included in subfield ‡a .

255 Scale 1:24,000.
255 Scales differ.
255 Scale not given.
255 Scale ca.1:63,360.
‡b Statement of projection

The entire projection statement.

255 Scale not given ; ‡b Conic equidistant proj.
‡c Statement of coordinates

The coordinates are recorded in the order of westernmost longitude, easternmost longitude, northernmost latitude and southernmost latitude.

255 Scale 1:250,000 ; ‡b Transverse Mercator proj. Everest spheroid ‡c (W 74˚50´ --W 74˚40´/N 45˚05´--N 45˚00´).
255 Scale 1:7,500,000 ‡c (W 125˚--W 65˚/N 49˚--N 25˚).

Entering coordinates. Use the following to create degrees, minutes, and seconds:

Symbol Action
Degrees Use the degree symbol.
Minutes Use a "miagkii znak."
Seconds Use the "tverdyi znak."

‡d Statement of zone

The statement of zone for celestial charts.

255 Scales vary ‡ d (Zones +90˚ to +81˚ to 63˚, -81˚ to 98˚ ; ‡ e eq. 1950).
‡e Statement of equinox

The statement of equinox or epoch.

255 Scale not given ‡ d (RA 0 hr. to 24 hr./Decl. +90˚ to -90˚ ; ‡ e eq. 1980).
‡f Outer G-ring coordinate pairs

Coordinate pairs that identify the closed nonintersecting boundary of the area covered.

‡g Exclusion G-ring coordinate pairs

Coordinate pairs that identify the closed nonintersecting boundary of the area contained within the excluded G-polygon outer ring.

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. For more information, see OCLC Catalog Cards at: /http://www.oclc.org/support/documentation/worldcat/cataloging/cards/.
