I'm interested to know about the book file option in Indesign, currently working on a book with 7 chapters, so I've created an indesign file for each of them, so then I'll drop them all into the book file. My question is can you preview the entire book in Indesign once they have been dropped into the book panel? Or can you only view one of those files at a time?
You can open all the chapters at once in InDesign. just keep double clicking on the icons in the book file palette. Put them in order and jump between them as you would multiple documents being opened at once.
