Might sound redundant, but it is not. A “History Book” is one that attempts to expound the events and possibly explain the connections and “whys” between them, so that the reader has a better understand of what has happened in the past and how we got here. Sometimes our understanding of past events changes when new information comes to light. This is generally a good thing, though sometimes more (but still incomplete) information confuses things from the initial simple or largely speculative view.
However, there are also people trying to rewrite history and make the ‘wrong” things go away, and constantly invent or “reinterpret” things in order to push a particular narrative. This is NOT good. It is something the SJW and Marxists do a lot.
so it is expected that what history books say will, to some degree, change over time. But the whole-sale revisions going on now are all the wrong type. So I think it might be good for people to make it a goal to accumulate or copy or locate or translate or make availible older history texts to that it is not lost. For example I came across one the other day – US History – in a used book store printed in 1904. That means there were still a considerable number of Civil War survivors around to point out flaws. Any bets I discover something in it that is not popular in today’s books?
