Abstract
Example methods and apparatus to implement electronic book viewers are disclosed. A disclosed example method involves presenting content on a display panel removably attachable to a binding element. The binding element is configured to receive one or more other display panels in a removably attached configuration to form an electronic book. The example method also involves enforcing a content protection policy associated with the content presented on the display panel based on an attachment status of the display panel. The attachment status is associated with the removable attachability of the display panel relative to the binding element.
