A patent granted to Google on Monday describes how Google Books might grant different access levels to books and magazines based on the location of viewers, according to Bill Slawski. The Google patent attempts to address copyright issues that often come into play when trying to enforce geographic and political boundaries. Slawski tells us copyright laws can differ per country. He details the patent "Variable user interface based on document access privileges" and provides some details on the metadata that might be created for the scanned magazine and book documents posted online.
