Abstract:

Content reuse enables technical communicators to create multiple deliverables from a single set of source documents. A key component of reuse is identifying which information belongs in which deliverable. Some customization is feasible with build tags (RoboHelp), conditional text (FrameMaker), topic reuse (FrameMaker and AuthorIT), and similar features.
