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?
Hate it. This happened to most Lois Duncan books, like adding random sentences referring to someone’s cell being at home or some such crap. Like, it was written in the 70s, I think readers can understand why the characters didn’t have freaking cell phones.
Oh, weird. I thought OP was referring mostly to morality changes, like taking out ableist/racist language or something. Why the hell would you retcon the setting like that? Do they really think people don’t understand that cell phones haven’t always existed?
