Sue, America, The Last Best Hope is more of a spine/walk through American history in three volumes by William Bennett. We’re focusing on the first two volumes, because they cover the most ground. (Mr. Bennett hadn’t planned on writing the third volume since the events were so recent [1990–], but many people were asking for it.)
teachme2learn, the amount of reading has been reduced some by using America, The Last Best Hope as the main books rather than trying to cover all those events with separate books. I do see an advantage of using the books in the first edition, though, if you think you may want to eliminate some to keep the list from being overwhelming. It might be easier to eliminate some books than to try to eliminate some portion(s) of the spine readings. Does that make sense?
