I'm curious why there's no clear "Spanish" in these ISBN visualizations; there's 2 slots for English, one for France, Germany, Japan, Soviet Union, China, etc. but no big one for Spain. Do we really have so few books in Spanish? Or is this a predominantly English distribution?<p>I say this as someone who grew up in Spanish libraries and book shops, surrounded and immersed in Spanish books, so it feels a bit strange to see the tiny bit we occupy in the world map here.
