Physical description information for an item that requires technical equipment for its use, and/or more granular description information of an item's material properties to facilitate access and discovery or to support collection management.
Coded physical information is contained in field 007 (Physical Description Fixed Field) and field 008 (Fixed-Length Data Elements).
The subfield $f definition was narrowed in 2022 in order to reduce redundancies with the following newer 34X fields that are now suitable for several former uses of field 340 subfield $f: 344 (Sound Characteristics), 345 (Moving Image Characteristics), 346 (Video Characteristics), 347 (Digital File Characteristics).
The field is repeated for each subfield $3 (Materials specified).
Multiple values from the same source vocabulary may be recorded in the same field in separate occurrences of subfields. Terms from different source vocabularies are recorded in separate occurrences of the field.
$a - Material base and configuration
Physical substance (e.g., acetate, canvas, clay, film, glass, vellum, or wood) and configuration (e.g., cartridge, chip, dot, fiche, globe, sheet, and audio-, magnetic-, micro-, ultra-, or videotape) on which the information is recorded.

$b - Dimensions
Measurements of the material configuration (e.g., 35 mm. (film), 12 inch (phonograph disc), 4" x 6" (microfiche)).

$f - Reduction ratio value
A specific indication of the size of a micro-image in relation to the original from which it was produced. Most commonly, it is expressed numerically as a reduction ratio (e.g., 16:1, 90:1) or as a magnification value (e.g., 16x, 90x). For such designations expressed in general terms, use field 340 subfield $q (Reduction ratio designator).

$g - Color content
Color characteristics of the content of a resource. Achromatic values (white, gray, and black) are considered to be colors.

$l - Binding
A method used to bind a published or unpublished resource, or other binding information. May be recorded using a controlled term or other structured description.
Additional unstructured (or textual) information on binding may be recorded in field 563 (Binding Information).

$n - Font size
The size of the type used to represent the characters and symbols in a resource.
Font size may be expressed in general terms (e.g., large print), or by specifying in addition the dimensions of the type measured in points (e.g., 20 point).
340 | ##$ngiant print (36 point)$2rdafs |
$o - Polarity
The relationship of the colors and tones in an image to the colors and tones of the object reproduced (e.g., positive, negative).

Capitalization - Terms contained in the various subfields are not usually capitalized, except for proper nouns such as names of months, etc.
Subfield was renamed "Reduction ratio value" and the definition narrowed to the use of the subfield for size of micro-images. This reduces redundancies with the following newer 34X fields and their subfields that are now used for several former uses of field 340 subfield $f: 344 (Sound Characteristics) subfield $c (Playing speed); 345 (Moving Image Characteristics) subfields $b (Projection speed), $c (Aspect ratio value), and $d (Aspect ratio designator); 346 (Video Characteristics); 347 (Digital File Characteristics) subfield $f (Encoded bitrate).
