For any kind of honest history, I’ve always told my kids to get books before 1930.
Good for you.
My Mom & Dad were born poor as dirt in the early 1920’s (Mom in S.Dakota to poor farmers & Dad in Tennessee to sharecroppers)and both served in WWII. Both hated FDR with a passion, though. I guess they were paleo-conservatives and just didn’t trust the Harvard screwheads that were so damn smart they let the country go to complete hell. They always steered me to the right places. That was their job.
