Old references should generally be updated to a reference to a later Ethnologue or to another reference. But there are a couple reasons why an old ref may be desired: An undated population figure or extinction may have been copied over since E17 (but not E16), and the out-of-date citation will provide some indication of how dated the figure is, or a date for the last speakers may be given.
