007 Physical Description Fixed Field

Description/Instructions

This field contains coded information about the physical characteristics of all cartographic material issued serially, including maps, atlases, and diagrams. Use of code "a" for map in byte 00 (subfield $a) determines the meaning of the remaining character positions in the field. For a complete list of the other possible 007/00 codes and their related data elements, see the 007 - General Information section.

The 007 field is repeatable to allow for coding different formats described in the record. A single record covering different map formats may include more than one 007 field to represent the different formats in subfields $d (color) through $h (positive/negative aspect). All subfields are "not repeatable" and must be coded.

This field is defined in MARC 21 for maps as a fixed-length field consisting of eight character positions. In the OCLC system the character positions have been assigned subfield code equivalents.

Definitions of character positions/subfield codes

00/$a Category of material

a Map

Code "a" is used for all cartographic materials issued serially.

01/$b Specific material designation (SMD)

d Atlas

g Diagram

j Map

k Profile

q Model

r Remote-sensing image

s Section

u Unspecified

y View

z Other

| No attempt to code

Atlas - Use code "d" to indicate that the item is an atlas. Atlases generally contain maps, related text, and other cartographic information.

Diagram - Use code "g" to indicate that the item is a diagram. A diagram is a graphic representation of numerical data, or of the course or results of an action or process. The term is sometimes applied also to maps characterized by much simplified, or schematic, representation.

Map - Use code "j" to indicate that the item is a two-dimensional map. A two-dimensional map is defined as a representation normally to scale and on a flat medium, of a selection of material or abstract features on, or in relation to, the surface of the earth or of another celestial body.

Profile - Use code "k" to indicate that the item is a profile. A profile is defined as a scale representation of the intersection of a vertical surface (which may or may not be a plane) with the surface of the ground, or of the intersection of such a vertical surface with that of a conceptual three-dimensional model representing phenomena having a continuous distribution (e.g., rainfall).

Model - Use code "q" to indicate that the item is a model, a three-dimensional representation of a real thing, either of the exact size of the original or to scale.

Remote-sensing image - Use code "r" to indicate that the item is a remote-sensing image which is an image produced by a recording device that is not in physical or intimate contact with the object under study.

Section - Use code "s" to indicate that the item is a section. A section is a scaled representation of a vertical surface (commonly a plane) displaying both the profile where it intersects the surface of the ground or some conceptual model, and the underlying structures along the plane of intersection, e.g., geological section.

Unspecified - Code "u" indicates that the special material designation for the map is not specified.

View - Use code "y" to indicate that the item is a view, a perspective representation of the landscape in which detail is shown as if projected onto an oblique plane.

Other - Use code "z" for an item for which none of the other defined codes are appropriate.

03/$d Color

a One color

c Multicolored

| No attempt to code

One color - Use code "a" to indicate that the map is one color.

Multicolored - Use code "c" to indicate that the map is multicolored.

04/$e Physical medium

a Paper

b Wood

c Stone

d Metal

e Synthetic

f Skin

g Textile

i Plastic

j Glass

l Vinyl

n Vellum

p Plaster

q Flexible base photographic medium, positive

r Flexible base photographic medium, negative

s Non-flexible base photographic medium, positive

t Non-flexible base photographic medium, negative

u Unknown

v Leather

w Parchment

y Other photographic medium

z Other

| No attempt to code

A one-character alphabetic code indicates the material of which the map is made.

Paper - Use code "a" to indicate that the material is any kind of cellulose-based paper.

Wood - Use code "b" to indicate that the material is wood. A material which is based on wood particles or fibers may or may not be considered wood. Consider particle board wood.

Stone - Use code "c" to indicate that the material is stone.

Metal - Use code "d" to indicate that the material is metal.

Synthetic - Use code "e" to indicate that the material is synthetic (e.g., plastic, vinyl). Code "e" is used for all man-made substances other than textiles.

Skin - Use code "f" to indicate that the material is animal skin or hide (excludes leather, parchment, and vellum). Synthetic materials which are made to resemble animal skin are coded as synthetic.

Textile - Use code "g" to indicate that the material is textile. It is used for all fabrics, whether made from natural or synthetic fibers.

Plastic - Use code "i" to indicate that the material is plastic.

Glass - Use code "j" to indicate that the material is glass.

Vinyl - Use code "l" to indicate that the material is vinyl.

Vellum - Use code "n" to indicate that the material is fine-grained unsplit lambskin, kidskin, or calfskin prepared especially for writing or drawing on.

Plaster - Use code "p" to indicate that the material is plaster. Mixtures of ground solids and plaster are also coded as plaster.

Flexible base photographic medium, positive - Use code "q" to indicate that the material is a flexible base photographic medium designed to render a positive image.

Flexible base photographic medium, negative - Use code "r" to indicate that the material is a flexible base photographic medium designed to render a negative image.

Non-flexible base photographic medium, positive - Use code "s" to indicate that the material is a non-flexible base photographic medium designed to render a positive image.

Non-flexible base photographic medium, negative - Use code "t" to indicate that the material is a non-flexible base photographic medium designed to render a negative image.

Unknown - Use code "u" to indicate that the physical medium of which the map is made is unknown.

Leather - Use code "v" to indicate that the material is an animal skin dressed for use.

Parchment - Use code "w" to indicate that the material is the skin of a sheep or goat prepared for writing on.

Other photographic medium - Use code "y" for a photographic medium other than those covered by one of the more specific codes "q," "r," "s," and "t."

Other - Use code "z" for dimensions for which none of the other defined codes are appropriate.

05/$f Type of reproduction

f Facsimile

n Not applicable

u Unknown

z Other

| No attempt to code

Facsimile - Use code "f" to indicate that the map is a facsimile which resembles the original in all aspects possible, but it is not the original.

Not applicable - Use code "n" to indicate that the item is not a reproduction.

Unknown - Use code "u" when the type of reproduction is unknown.

Other - Use code "z" for a type of reproduction for which none of the other defined codes are applicable.

z Other

| No attempt to code

A one-character alphabetic code indicates the photographic technique used to produce the map.

Photocopy, blueline print - Use code "a" to indicate that the map is a photocopy, blueline print. This has blue lines with a white background. Bluelines are made from vellum, film positives, or any translucent or transparent original on which an image has been made and reproduced by the whiteprint process.

Photocopy - Use code "b" to indicate that the map is a photocopy of the original.

Pre-production - Use code "c" to indicate that the map is a pre-production (proof) copy intended for review.

Unknown - Use code "u" to indicate that the production/reproduction details are unknown.

Other - Use code "z" for production/reproduction details for which none of the other defined codes are appropriate.

07/$h Positive/negative aspect

| No attempt to code

A one-character alphabetic code indicates the positive/negative aspect of the photocopy or film item if a map. This characteristic is also referred to as polarity.

Positive - Use code "a" to indicate that the polarity is positive, i.e., lines and characters are dark on light background.

Negative - Use code "b" to indicate that the polarity is negative, i.e., lines and characters are light on dark background.

Mixed polarity - Use code "m" to indicate that the photocopy or film is a mixture of positive and negative images.
