A graphical user interface (GUI) element is displayed on a display screen (e.g., a touchscreen) of a computing system (e.g., an electronic-book reader). In response to the GUI element being selected by a user, different items of content are accessed. A duration value that indicates a length of time is associated with each item of the items of content. Information identifying at least a subset of the items of content is displayed on the display screen, where the subset is selected according to the duration values. |
