Guide to Cataloging DVD and Blu-ray Discs Using AACR2r ... - OLAC

Example:
006 m d f
The only possible elements in this field are:
00 Type = m (Computer files/Electronic resources)
05 Audience (in this example, blank = unknown or unspecified)
09 File (in this example, d=document)
11 Government Publication (in this example, f=federal)
B. 007 Fixed-length Data Elements -- Physical Characteristics
(Electronic Resource) (Required; Repeatable)
This field is used to identify the physical characteristics of the DVD-ROM in a coded
form. The category of material should be coded “c” for computer file, with the specific
material designation coded “o” for optical disc and dimension coded “g” for 4 3/4 in. Add
the appropriate codes for color and sound.
The coding for the 007 is explained in MARC 21 Format for Bibliographic Data
as well as the OCLC Bibliographic Formats and Standards
MARC OCLC Subfield Code
007/00 $a category of material c=electronic resource
007/01 $b specific material designation o=optical disc
007/03 $d
color
b=black & white
See MARC 21 for additional codes c=multicolored
007/04 $e Dimensions
g=4 ¾ in.
z= other (use for 3 in. disc)
007/05 $f sound a=sound
C. 008 Fixed-length Data Elements
(Required; Not Repeatable)
(In mnemonic form, the Leader plus the 008 is represented as the “fixed field.”)
If the DVD-ROM does not consist of programs or multimedia and the Leader/06
character position is coded something other than “m,” be sure to code the 008/23
(Form of item) character position “s” for “Electronic.” If the Leader/06 character
position is coded “m” (for computer file), be sure to identify the Type of computer file
from the choices provided in MARC 21 008/26.
