I have an InDesign CS6 Book. I need to use "Save Book As" to make a copy of it, and I need to slightly expand the trim size of the new copy for a different use. I don't want this change to happen in the old copy. I notice that changes you make to one book's documents are reflected in copies of that book. How do I turn this off and "unlink" the two copies? Thank you.
Either make a new .indb file and add the copies of the prioginal compoent files files to it (and delete the copied .indb file so you don't accidentally use it and change something you didn't intend to change). or Package the book to make a copy of everything and automatically update the links in the package to the new copies automatically.
Packaging the book did it, thank you!
