Given the trend we've seen towards dictionaries rewriting definitions of words and sites like Wikipedia scrubbing long-existing content in the name of combating "misinformation", I'd like to have a set of older hardcopies of encyclopedias and dictionaries so things that are being erased are still preserved somewhere.
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)
