I'm being presented with ARs for a name with a variant parenthetical designation as a 400, e.g. "100 Name (Teacher of mathematics)" and "400 Name (Mathematician)"; in another case "100 Name (Pianist)" and a newly added "400 Name (Composer and pianist)" in response to information presented in a newly cited source.
This doesn't seem quite right somehow, but I can't find any positive negative example (so to call it) to justify my uneasiness.
With thanks from a less than coordinated Acting NACO Coordinator -
