A handheld electronic book reader, program product, and method incorporate enhanced annotation and/or usage tracking capabilities. Users may create “contexts” for defined terms in an electronic document. Moreover, annotation data such as contexts, comments and highlighting may be associated with various users, and displayed in connection with the display of an electronic document so as to indicate that different annotation data has been originated by different users. In addition, from the standpoint of usage tracking, usage statistics for an electronic document displayed in a handheld electronic reader may be generated on a page-by-page basis, and/or in association with term definitions. Moreover, usage statistics for multiple users may be combined and analyzed. Through such analysis, the usage statistics may be used in the conduct of various beneficial actions such as revising an electronic document, revising a lesson plan with which an electronic document is associated, determining whether a user has read a selected portion of an electronic document, or determining whether a user needs supplemental assistance. |
