Abstract
Some implementations include identifying conflicts between multiple layers of supplementary content associated with a digital work (e.g., an electronic book). For individual conflicts between layers of supplementary content at one or more locations within the digital work, conflicts between layers may be resolved in favor of a higher priority layer. Upon resolution of the conflict, information associated with the higher priority layer for supplementing content at a particular location in the digital work may be determined. A visual identifier of the higher priority layer may be displayed along with content associated with the digital work at the particular location.
