You can also export your book as a PDF file, which can be viewed or printed using Preview, Adobe Reader, or any PDF reader application. Hyperlinks work in the PDF, but other interactive media and widgets will be static.
Sharing individual chapter of collaborative books. I typically have each student export their individual chapter as a PDF using iBooks Author's built in export tool. Then we upload the PDF version of their chapter to SlideShare. Students then use Slideshare to embed a viewable version of their chapter in their final reflection post on the publishing project. See samples from our class WordPress site here. Note: While the chapters are static PDFs, it does create a showcase of their iBook chapter for viewers without Macs, iPads or iPhones. It also serves as searchable source for their individual topic.
You can also export only the text from your book.
