That's one nice thing about hardcopy. It can't be changed remotely.

You can get a complete self-contained offline snapshot of Wikipedia (and many other wikis and websites) from https://www.kiwix.org/

Do you have a reference for the trend of dictionaries rewriting words? Is it any different then dictionaries keeping up with the way language is being used in the present? Also, don't new definitions usually get added on top of the older ones? (E.g. literally meaning both literally and figuratively now)

Wikipedia does at least preserve history.

Not always. Deleted articles are gone including the edit history, for example.
