> It's an overview of what we know about Proto Indo-European and its spread across the world. That's a bit misleading isn't it? PIE died out a long time ago. And it certainly didn't spread all over the world. It's descendent languages moved into india, middle east and europe. And it's european languages ( primarily spanish, french and english ) that went global. Nobody would say Latin went global just because spanish is spoken around the world. Or old english went global because much of the world speaks english. But thanks for the recommendation.
