In George Orwell’s 1984, protagonist Winston Smith secretly obtains a copy of what is known as “the book” in his quest to learn the truth about the dystopian world in which he lives. His inquiry is cut short, however, when he is arrested by the Thought Police for reading the forbidden text.
Paradoxically, if you locate 1984 with Google Book Search and try to read the novel online, you will likely experience an Orwellian moment. After viewing just a few pages, the following warning appears: “You have either reached a page that is unavailable for viewing or reached your viewing limit for this book.” While nothing found on Google Book Search is banned (not yet, as far as we know), obviously someone, or more accurately something, is watching you! …
