Synchronize book documents

Last updated on Jun 2, 2026

Learn how to use the style source in Adobe InDesign to update styles, swatches, and parent pages across all documents in your book.

Synchronizing updates shared items from the style source by replacing matching items, adding new ones, and leaving others unchanged. Closed documents update automatically, while open documents require manual saving.

Synchronize early to maintain parent page overrides. Use a single style source or disable parent page synchronization when changing sources or names.

Select synchronization options

Open an InDesign book (INDB) file.

Select the Book panel menu and then select Synchronize Options.

Select the items you want to copy.

Select Smart Match Style Groups to prevent duplication of uniquely named styles that have been moved into or out of style groups.

Tip

Select all styles referenced by others to ensure complete synchronization across related categories.

Select OK.

Synchronize documents with the style source

Open an InDesign book (INDB) file.

In the Book panel, select the blank box next to a document to designate it as the style source.

The open Book panel showing a list of three book documents, and the style source icon highlighted next to one document.
Designate a document as the style source to display the style source icon next to it.

Select the documents to synchronize with the style source. Select any blank area to synchronize the entire book.

To preserve unique parent page items, exclude those documents from synchronization or create parent pages with different names.

Select Synchronize Selected Documents or Synchronize Book from the panel menu. InDesign updates all selected documents with the specified elements from the style source.
