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?
Generally, I’m for it! But I agree it should be explicitly labeled as a revised version. I would especially love updated versions edited to remove outdated language/stereotypes/slurs. For example, you’d be hard-pressed to find a non-revised Nancy Drew book. I don’t really care if it’s the author or a ghostwriter doing it, a long as it’s labeled. As for updating it strictly to keep up with the times, like changing a rotary phone to a mobile, I’m not really interested in that, but it’s also not… harmful. Like, I don’t care that much.
