007 Physical Description Fixed Field

Description/Instructions

This field contains coded information about the physical characteristics of projected graphic material (e.g., slides, filmstrips). Use of code "g" for projected graphic 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 projected graphic formats may include more than one 007 field to represent the different formats in subfields $d (color) through $i (secondary support material). All subfields are "not repeatable" and must be coded.

This field is defined in MARC 21 for projected graphics as a fixed-length field consisting of nine 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

g Projected graphic

Code "g" indicates that the item is projected graphic material which is defined as a two-dimensional representation intended to be projected without motion by means of an optical device, for example, a filmstrip, slide, or transparency.

01/$b Specific material designation (SMD)

c Filmstrip cartridge

d Filmslip

f Other type of filmstrip

o Filmstrip roll

s Slide

t Transparency

z Other

Filmstrip cartridge - Use code "c" to indicate that the item is a filmstrip which is encased in a cartridge and which has the ends joined to form a loop. A cartridge denotes a permanently encased single reel of film or tape that has the ends joined together to form a loop that provides playback without rewinding.

Filmslip - Use code "d" to indicate that the item is a filmslip which is a short filmstrip not in a roll.

Other type of filmstrip - Use code "f" to indicate that the item is a filmstrip other than a filmstrip cartridge, filmslip or filmstrip roll.

Filmstrip roll - Use code "o" to indicate the item is a filmstrip roll, a roll of film on which still images are recorded, presenting an integrated communication. It is intended for projection frame by frame.

Slide - Use code "s" to indicate that the item is a slide. Slides are transparent material on which there is a two-dimensional image, usually held in a mount, and designed for use in a projector or viewer. Modern stereographs (e.g., Viewmaster reels) are included here.

Transparency - Use code "t" to indicate that the item is a transparency. Transparencies are made of transparent material on which an image is recorded. They are designed for use with a projector or a light box. X-rays are included here.

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

03/$d Color

m Mixed

u Unknown

z Other

One color - Use code "a" to indicate that the image is printed or executed in a single color (i.e., monochromatic), other than black. In projected graphic materials, it is used only for transparency sets.

Black-and-white - Use code "b" to indicate that the image is printed or executed in black-and-white. It refers to monochrome photographic materials (including film) and videorecordings, or to overhead transparencies executed in black-and-white. If the item has been tinted, toned, or stained, code "z" is used.

Multicolored - Use code "c" to indicate that the image is printed or executed in more than one color. The color is a result of a number of processes, either photographic or electronic, capable of reproducing a reasonable range of hues, or of original application of color materials, for example, paint. Code "c" is used for color photographic processes (motion pictures, filmstrips, transparencies, and slides), color videorecordings, or multicolored overhead transparencies.

Hand colored - Use code "h" to indicate that the image, produced by a printing or photographic process, is hand colored. Code "h" is rarely used with commercial audiovisual materials since these are not typically issued with hand coloring.

Mixed - Use code "m" to indicate that the work or collection is a combination of one color, black and white, colored, hand colored, and/or other images. Information for this data element is based on one of the following phrases: some col., some b&w, 25 gold toned, col. with b&w sequences, etc. which usually appears in other parts of the MARC 21 record.

Not applicable - Use code "n" to indicate that the item has no images. It is used, for example, when the item in hand is sound track film intended to accompany visual images not actually present.

Unknown - Use code "u" if the color characteristics of the projected graphic are unknown.

Other - Use code "z" for an item for which none of the other defined codes are appropriate. For example, code "z" is used for images which have been stained, tinted, or toned (e.g., sepia toned photographic items).

04/$e Base of emulsion

d Glass

e Synthetic

j Safety film

k Film base, other than safety film

m Mixed collection

o Paper

u Unknown

z Other

A one-character alphabetic code indicates the type of material for the base of the emulsion of a photonegative, filmstrip, slide, or transparency. The codes described below are used for filmstrips, slides, transparencies, and other projected graphics.

Glass - Use code "d" to indicate that the primary support/base of the emulsion material is glass.

Synthetic - Use code "e" to indicate that the primary support/base of the emulsion material is synthetic (e.g., plastics, vinyl, etc.). Most commercially issued overhead transparency sets have a synthetic primary support material, unless known to be otherwise.

Safety film - Use code "j" to indicate that the primary support/base of the emulsion material is safety (i.e., not nitrate) film. For all commercially issued filmstrips and slide sets, assume that the base of the emulsion is safety film unless known to be otherwise.

Film base, other than safety film - Use code "k" to indicate that the primary support/base of the emulsion material is not safety film.

Mixed collection - Use code "m" to indicate that the primary support/base of the emulsion material varies for different items in a collection. Typically this would be used for groups of projected graphics on various bases.

Paper - Use code "o" to indicate that the primary base of the emulsion is any kind of cellulose-based paper.

Unknown - Use code "u" if the primary support/base of the emulsion material for the projected graphic is unknown.

Other - Use code "z" for an item for which none of the other codes for primary support/base of emulsion material is appropriate.

05/$f Sound on medium or separate

# No sound (silent)

a Sound on medium

b Sound separate from medium

u Unknown

A one-character alphabetic code indicates whether the sound of the projected graphic is on the item or separate from the item (i.e., on the accompanying material).

No sound (silent) - Use code "#" to indicate that sound is not present.

-- For filmstrips, slides, and transparencies, code "#" is used when there is no information concerning sound in subfield $b or $e of field 300 in AACR2 formulated records.

-- For kits containing any of the above items, the abbreviation si. or the fact that there is no statement pertaining to sound in field 500 (General Note) justifies use of code "#."

Sound on medium - Use code "a" to indicate that sound is present and is on the item.

Sound separate from medium - Use code "b" to indicate that sound is present but it is on the accompanying item.

Unknown - Use code "u" if the presence of sound on the item is unknown.

06/$g Medium for sound

# No sound (silent)

a Optical sound track on motion picture film

b Magnetic sound track on motion picture film

c Magnetic audio tape in cartridge

d Sound disc

e Magnetic audio tape on reel

f Magnetic audio tape in cassette

g Optical and magnetic sound track on motion picture film

h Videotape

i Videodisc

u Unknown

z Other

A one-character alphabetic code indicates the specific medium used to carry the sound of an item whether that sound is carried on the item itself or is in the form of accompanying material. It also indicates the type of sound playback required for the item. This character position is used in conjunction with the information coded in 007/05 (Sound on medium or separate) and 007/07 (Dimensions).

Typically, the carriers of sound are: 1) optical and/or magnetic track on a film reel or encased in a cassette or cartridge; 2) audio or video tape which may be on a reel or encased in a cassette or cartridge; and 3) sound or video disc.

No sound (silent) - Use code "#" to indicate that sound is not present.

Optical sound track on motion picture film - Use code "a" to indicate that sound to accompany a projected graphic is carried on an optical track that is part of a film. In coding 16 and 35 mm. films, it is usually assumed that sound is carried on an optical track.

Magnetic sound track on motion picture film - Use code "b" to indicate that sound to accompany a projected graphic is carried on a magnetic track that is part of the film. 70 mm. motion picture films often include magnetic sound tracks.

Magnetic audio tape in cartridge - Use code "c" to indicate that sound to accompany an item is carried on a magnetic audio tape cartridge.

Sound disc - Use code "d" to indicate that sound to accompany an item is carried on a sound disc. This method of providing for sound is typically used with filmstrips. Sound discs include 7, 10, and 12 in. vinyl phonograph records (identified as analog sound discs in subfield $a of field 300) and 4 3/4 in. compact discs (identified as digital sound discs in subfield $a of field 300).

Magnetic audio tape on reel - Use code "e" to indicate that sound to accompany an item is carried on a reel of magnetic audio tape.

Magnetic audio tape in cassette - Use code "f" to indicate that sound to accompany an item is carried on a cassette of magnetic audio tape.

Optical and magnetic sound track on motion picture film - Use code "g" to indicate that sound to accompany a projected graphic is carried on both an optical and magnetic track.

Videotape - Use code "h" to indicate that sound to accompany an item is included as part of a videotape. Videotape is not ordinarily used to record only sound.

Videodisc - Use code "i" to indicate that sound to accompany an item is included as part of a videodisc. Videodiscs are not ordinarily used to record only sound. A distinction must be made between videodiscs (e.g., 12 in. laser-scan videodiscs that include video information) and compact discs that are used to record sound only (e.g., 4 3/4 in. audio compact discs). The technology to physically record video or audio information on digital disc systems is the same.

Unknown - Use code "u" if the medium for sound is unknown or cannot be determined by examining the item.

Other - Use code "z" for a medium for sound for which none of the other defined codes is appropriate.

y 7x7 in. or 18x18 cm.

A one-character alphabetic code indicates the width or dimensions of the projected graphic item. Width is given for filmstrips. Height and width are given for slides and transparencies. Only the most common dimensions are indicated.

For film and slides, only codes that exactly match the measurements of the item as given in the physical description should be used. If no code exactly matches, code "z" is used. For transparencies, the code that most closely approximates the dimensions as stated in the physical description is used. The dimensions for slides and transparencies include the size of the mount for the item.

Standard 8 mm. - Use code "a" to indicate that the width of the film is standard 8 mm. Film termed "Mauer 8 mm." is recorded as code "a."

Super 8 mm./single 8 mm. - Use code "b" to indicate that the width of the film is super 8 mm. Single 8 mm. film is a Japanese equivalent of super 8 mm. film.

9.5-70 mm. - Use codes "c," "d," "e," "f," and "g" to indicate that the width of the film is equal to one of the defined widths in millimeters.

2x2 in. or 5x5 cm. - Use code "j" to indicate that the dimensions of the slide in its mounting are either 2x2 in. or 5x5 cm.

2-1/4 x 2-1/4 in. or 6x6 cm. - Use code "k" to indicate that the dimensions of the slide in its mounting are either 2 1/4 x 2 1/4 in. or 6x6 cm.

4x5 in. or 10x13 cm., etc. - Use codes "s," "t," "v," "w," "x," and "y" to indicate that the dimensions of the transparency are close approximates to the dimensions the specific code represents.

Unknown - Use code "u" if the dimensions are unknown.

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

08/$i Secondary support material

# No secondary support

c Cardboard

d Glass

e Synthetic

h Metal

j Metal and glass

k Synthetic and glass

m Mixed collection

u Unknown

z Other

A one-character alphabetic code indicates the type of material of the mount of a slide or transparency for a projected graphic.

No secondary support - Use code "#" to indicate that there is no secondary support. Filmstrips are always coded "#."

Cardboard - Use code "c" to indicate a cardboard mount. Slides and transparencies cataloged from data sheets are assumed to have cardboard mounts unless otherwise known.

Glass - Use code "d" to indicate a glass mount. The glass mount usually covers the film base but should not be the primary support for the film emulsion.

Synthetic - Use code "e" to indicate that the secondary support material is synthetic (e.g. plastics, vinyl, etc.).

Metal - Use code "h" to indicate that the secondary support material is metal. Metal is usually used to frame larger projected graphics which need better support.

Metal and glass - Use code "j" to indicate that the secondary support material is metal and glass. The metal portion is usually a frame that holds one or two pieces of glass to support the film base. The glass should not be the primary support for the film emulsion.

Synthetic and glass - Use code "k" to indicate that the secondary support material is synthetics and glass. The synthetic material, e.g., plastics, vinyl, etc., is usually used as a frame to hold one or two pieces of glass to support the film base. The glass should not be the primary support for the film emulsion.

Mixed collection - Use code "m" to indicate that the secondary support material varies for different items in a collection. Typically this is used for groups of projected graphics on various secondary support materials.

Unknown - Use code "u" if the secondary support material is unknown.

Other - Use code "z" for a secondary support material for which none of the other defined codes are appropriate.
