A method for indicating changes in a structured document includes identifying a new topic or a modified topic in an updated version of a structured document having one or more topics, generating a table of contents having one or more topic entries associated with the one or more topics, marking a topic entry associated with the new topic or the modified topic with a marker indicating that the associated topic is new or modified. A system includes an unmarked table of contents having an entry associated with a unit of updated topic content, and a marking module marking the entry if the unit of updated topic content has changed or the unit of updated topic content comprises a new topic.
