Ah, thanks for the clarification, and a big thanks for keeping us moving!
I think the clearer we can be, the better, so let’s go with what you have!
I’ll resend the invites by tomorrow latest.
As for the questions about the license on the webbook: I’ve heard back from Pressbooks, and it appears that the chapter title does, in fact, override the book title in the chapter-level copyright license when a chapter author is added to the metadata, but this only happens when the chapter’s license has been set to something other than the book’s license. As an example, if the book is CC-BY, but the chapter was set to CC-BY-SA, the chapter title would appear in the license statement. However, since in this case, both the book and the license are CC-BY, only the author’s name appears in the license statement. The team at Pressbooks sees clearly the use-cases like ours, and will be considering ways to update this feature in the longer term. Given our timelines with this book, however, they have suggested that we remove the authors from chapter-level metadata, so the license statement is consistent on all the pages, and instead add author names manually to the beginning of a chapter’s body, so the chapter authors are still duly credited for their contributions. I’ll note that if we do make the manual additions, it would be best to format the author names as either a heading 2 or paragraph style, so the content is organized logically (see more about Organizing Content in the Accessibility Toolkit). Hope this helps!
