A7. Nonbook formats
Do not apply the code "dcrmb" to records for nonbook materials such as serials, maps, music, and graphics, even though they may have been cataloged according to an adapted, "DCRM(B)-like" standard (FNA-1). Do, however, apply the code "dcrmb" to individual and special issues of serials cataloged separately as monographs according to the provisions of Appendix H.
