LC-PCC PS: Serial number:
Record a serial number if works with the same title and the same medium of performance are consecutively numbered in music reference sources.
Record serial number if works with the same title for different media are consecutively numbered in music reference sources if the medium of performance is omitted from the authorized access point per 6.28.1.9.1 exception a) ii)
