This question probably would have worked best in a writing forum, but what is the most straightforward and clear way to discuss a person in a proof when sources spell the person's name (given or surname) differently, as they often do?
I find that some authors:
use quotation marks within the sentence when referring to the differently spelled name to the source, others add [sic] after the varied spelling, and others use neither of these, perhaps supposing the reader will pick up on this by simply reading the citation.
Some make a catch-all citation or statement in the proof saying that discussions in the text will use "x" spelling for the purposes of the article.
We always record accurately the name as spelled in the citation; but what is the most elegant way to handle this in the writing when referring to said differently spelled sources?
That was a mess to explain, but I'd appreciate your feedback on untangling!;)
