ZombieList records will always use the Tag Field for the Status and Source: the dash for –Status: and dot for .Status: . Status tags always use -Status: : Original, Alive, Asleep, Sold, Lost, or Zombie. Note: a record can have Zombie in addition to a Live, Asleep, or Sold, if the source had changed its title, format, or status. When a source has NOT changed its title, format, or publisher, then that source is still alive, but not a Zombie.
Source tags always use .Source: . Whenever the item is mentioned in a core bibliographic give the record a source tag. At least one of the records in ZombieList entry should have a .Source: tag. Only add a Source tag if when the item is mention in the bibliography you are using.
The Tag Field might also contain LC Subjects.
