Our group is finishing up the iBook version to our book. Our epub was finished this morning when we had to fix some spaces on the copyright page and add the final metadata in Sigil.
We are each inputting the text (from an HTML file) into our assigned chapters as well as adding an image for the chapter title and any other images we might have found. Once Emily finishes the last chapters, Will plans on going through and bookmarking all of the extra TOC references and making them links. This is an additional feature that will be completed if we have enough time.
