Claim:
1. A system comprising tangible, non-transitory computer-readable storage media encoded with code that, when executed by a processor, causes the processor to: define an electronic book (e-book) with sections, navigation controls and a path selector; receive a path-change command to change an active path from a first path to a second path, each of said paths corresponding to a respective series of sections of said e-book linked in an order, said first path differing from said second path in the order of the sections included therein; and in response to said path-change command, change said navigation controls so that they provide for navigation along said second path instead of along said first path, wherein said e-book includes a control that, when activated, presents a graphical interface for creating a new path including at least some of said sections, the graphical interface including a map of said sections and links between said sections.
