Consider books in the vein of Hardy Boys[1]. Many of these books get revised over the years by the publisher. Imagine if the book on your shelf changed and when you went to read it again, the prose differed from how you remembered. People can disagree as to the extent to which the changes are good or bad (some are clearly fixes for "whoa, that was racist even for the year it was published" others are claimed by the original authors to have stamped out the small bit of originality they were able to slip past the editors), but something is lost when you lose things the way they were originally experienced.
