Abstract: An interactive graphical user interface for navigating an electronic textbook includes nodes and connectors connecting the nodes. The nodes may correspond to items of educational content, and the connectors may correspond to a plurality of paths through the nodes. As a user navigates through the electronic textbook, the user may be presented with a custom map of the electronic textbook. A path of traversal may be permanently stored.

Abstract: An electronic textbook includes nodes containing items of educational content, and a plurality of paths through the nodes. Each path represents a different organization of the nodes in the electronic textbook. The paths are tailored to the educational needs of the users of the electronic textbook. As a user traverses the nodes of the electronic textbook, the user creates a personalized path. The user can add comments to the nodes and connections of this path. These paths and associated comments are made available to other users of the electronic textbook.
