Conspiracy: #3 listed in an encyclopedia as the common cold?

This video clip is older, so the death statistics aren’t up to date, also I understand that covid-19 is a new version of the corona virus but this doesn’t change the fact that it was listed as the common cold in an encyclopedia from the 1980s. This is why I think that actual physical books are still very necessary; digital information can be constantly deleted, manipulated and altered but information in physical books stand as proof. Do you know anyone personally that has covid-19? I know of no one. I’m still sheltering in place and I don’t have the answers but I’m asking myself, what is really happening?
