Mistakes happen. It's surprising that it has gone on this long, but I guess they don't have any reason to go back and read a book that was edited 44 years ago. I've read this book before and don't remember noticing it myself. It is too bad though since this is a new edition. Can they not change it for later printings of the LT edition, or is that too much trouble?
I've never heard the Bolivarian term, but I don't really know a whole lot about that area and it's history.
