Probably the best example I can think of is Diane Duane reworking her Wizards series to make it modern-day, but there are others, including owners of a literary estate altering books left to them to make them compatible with current standards.
What do you think? Does it matter if it’s the original author or an inheritor?
But the whole point is that 80s you learnd that we used to have to use belts. Maybe ask an older lady about a belt and have a good story and a laugh.
I guess that depends on whether the book is an artifact of its time or a functional tool for the reader. I think it’s both, so it gets messy.
