Sorry, but I disagree with you vehemently. The library has bought the book on the basis that it will be "loaned" to readers, not permanently kept. If you keep it, that is just as bad a downloading a copy of it illegally. It's a matter of trust - libraries do not exist to GIVE you books, but to LOAN them to you. If you violate that trust, you're putting the entire library eBook system at risk, and reinforcing the idea that users are all criminals who will steal if given half a chance. You damage everybody by doing this, and merely strengthen the idea in the minds of publishers that DRM systems are necessary.
