When submitting a manuscript for professional publication, should the author use underlines or italics?
Before the age of computers, underlining was the rule, of course. But back in the late ’80 when home computers were not quite the norm and dot matrix printers were still king, at least one profession author recommend always to underline. Italic print could be easily overlooked by the typesetters used to seeing underlines.
Nowadays things might be different. Which should be used? Assume the author is writing before finding a publisher and doesn’t have specific guidelines.
