日本の村ー須恵村 / ジョン・F.エンブリー著 ; 植村元覚訳 = Suye mura : a Japanese village / by John F. Embree. (OCLC #881293935)

The translator of this book died in 1997, but this is not reflected in the authorized access point:

    Uemura, Motokaku, 1916-

This is not unusual. RDA 9.19.1.3 says about adding dates to access points:

    Add the date of birth and/or date of death if needed to
    distinguish one access point from another.

LC-PCC practice for new authority records is to add a date of birth and/or date of death to new authority records, even if not needed to distinguish between access points, but not necessarily to add them to existing records (though the option is there).

The VIAF cluster shows that some vocabularies (Japan’s National Diet Library, ISNI) have added the death date. When our catalogs have more of a “things not strings” model and store URIs for access points (rather than the full text of the authorized access point), such changes will be less costly to make.
