Reply To: InDesign Book Feature

The benefits of using the Book panel include abilities to synchronize styles and swatches across all documents, to automatically update all page numbering, to output all docs to a single PDF, and to package all assets associated with the project. If any of those sounds like it would be useful, it might be worth trying. Alternatively, you can do all those same things by putting everything in one file, but then only one person can be in the file, and if the document ever went corrupt, missing, etc, you have bigger problem than if it was just a single chapter. Hope that helps.
