Use of GMDs 
 
GMDs are only used in the title proper field (245).
 
Order of ‡:   a,n,p,h,b,c.
 
Edit out GMDs found in other fields as encountered in older bib records, i.e.:
If you find ‡h in added entry 7XX fields, delete.
If you find ‡h in 246 fields, delete.
If you find ‡h in 240 fields, delete.
 
----------
‡h [electronic resource]
replaces former GMD [computer file] as of Dec. 2001.
 
LCRI says LC uses only selected terms from the list of possible GMDs in AACR2r.  The selected terms are:
electronic resource
filmstrip
kit
microform
motion picture
slide
sound recording
transparency
videorecording
 
Library or Departmental policy on use of GMDs has not been consistent. Gov. Doc uses AACR2R list. CatSS accepts whatever is in the records which they import from utilities.
 
Catalogers affirmed GMD policy for original cataloging in September, 2003.We will follow the LCRI practice, with two exceptions:  catalogers may use any appropriate GMD for items cataloged for Special Collections which are given ART or PHOTOGRAPH accession numbers.
 
Here is the entire list of GMDs in AACR 2R 1.1C (thanks to Michael)
