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.
