USMARC Concise Bibliographic: Control Field 007



007 - PHYSICAL DESCRIPTION FIXED FIELD--GENERAL INFORMATION (R)


The physical characteristics of an item, usually derived from explicit information in other fields of the record, expressed in coded form. The data elements are positionally defined, and the number of character positions in field 007 and the definition of each depend upon the code contained in 007/00 (Category of material). Each defined character position contains either a code or a fill character ( | ). Code u (Unknown), when it is defined for a data element, indicates that the position definition does apply to the record but that information needed to code the position correctly is unknown. Code n (Not applicable), when it is defined for a data element, indicates that the character position definition does not apply to the specific class of material coded in 007/01.
The categories of material for which field 007 is applicable in bibliographic records are presented in the following order in the field description: map, globe, projected graphic, microform, nonprojected graphic, motion picture, sound recording, text, videorecording, unspecified.

007--REMOTE-SENSING IMAGE


Indicates that the item is a remote-sensing image which is defined as an image produced by a recording device that is not in physical or intimate contact with the object under study. This may be a map or other image that is obtained through various remote sensing devices such as cameras, computers, lasers, radio frequency receivers, radar systems, sonar, seismographs, gravimeters, magnetometers, and scintillation counters.

007--SOUND RECORDING


A disc, tape, film, cylinder, or wire on which sound vibrations have been registered so that the sound may be reproduced; and paper rolls on which the notes of a music composition are represented by perforations in the paper and from which sound can be mechanically produced.
