Can more than one person work on the same book? - On Premises 6.4

FAQs - On Premises

Yes. Although only one person at a time can make changes to the properties of the Book, any number of its topics may be edited simultaneously by different authors. The simplest and best way of managing multiple authors is to create separate sub-books, and assign each author to work within their own sub-book. Author-it seamlessly stitches the sub-books together when you publish your outputs.
