I think it is important to preserve history as best we can because certainly it is being destroyed. Perhaps time to purchase American history books to pass on to our children and grandchildren before that information is made unavailable. I browsed Amazon and there are quite a few books available right now on American history. I can forsee that changing in the future as well as demands on schools and libraries to deplete their inventory of history books.
I have a couple of historical type books sitting on the shelves already; "Oliver North Mission Compromised", "American Soldier, General Tommy Franks" (my fave), "Flags of Our Father", "Chris Kyle American Gun", "The Revolution, Ron Paul", "America the Beautiful" ..... but I think I want to purchase a couple of books with a complete history of America.
