Devices and methods are provided for displaying digital publications and related information. In one embodiment, the method may involve: receiving a user selection for at least one of a digital publication and a new location within the publication; loading tiles into a viewing area of a display page, each tile comprising graphic page information for the publication; and calculating a center location of the viewing area. The method may involve: identifying a center tile in which the center location is located; calculating a time lag corresponding to how long the center tile has been viewed by a user; and in response to the time lag being equal to or greater than a defined time period, displaying selected data on the display page, the data being selected based at least in part on the graphic page information displayed in the center tile.
