That’s amazing news! As for the formats, I’d suggest exporting all the formats expect EPUB3 and HTMLBook (as these are still in beta). With the other formats, we give readers the option of reading on the web, in their LMS with the Common Cartridge 1.1 (web links) format, via editable formats like XHTML, ODT, XML, or EPUB, or offline too with PDF, MOBI.
I’ll note that the Pressbooks team has just given me a small update on the licensing statement at the chapter level. It looks like they’ve updated a feature, so if you select the appropriate license for a chapter in the chapter metadata (even if this is the same as the global license) and enter the corresponding chapter author, the license statement for this chapter in the webbook should display as “[Chapter Title] by [Chapter Author] licensed [selected license].” This was I think the desired behaviour on our end, though there’s a need to re-enter the CC BY license in each chapter’s metadata. If you wanted, you could apply this change before pulling the final exports. I’ve enquired to find out whether this change will affect other formats too — I don’t think it will, but of course wanted to confirm with the Pressbooks team!
Thank you for the final print PDF page count. I’ll re-calculate the dimensions for the print cover, and pass it along to Jonathan!
Quick note that I’ll be out of office next week, but if you did want to keep moving on this book in the meantime, @zoe or @LeighKP will be more than happy to help with anything you need!
