Dear Google Books user,
Please bear with us while we figure out this whole “QR Code” thingy. Thanks.
Submitter comment: QR Codes on Google Books appears to be a generic thing on every page, but why put a QR code on a web page when I’m already online? Oh, it’s a link! Maybe I can just click on it instead of scanning it! So I clicked on it, got this magnified image file, and fell over laughing.
