古登堡计划创始人Michael S. Hart曾经写过一段话:
"大多数人没有意识到,电子书有一个特点。它是人类有史以来,制造出来的第一种像空气一样取之不竭的产品。如果你仔细思考这一点,你就会意识到,我们正在做正确的事情。"(One thing about eBooks that most people haven't thought much is that eBooks are the very first thing that we're all able to have as much as we want other than air. Think about that for a moment and you realize we are in the right job.)
