How to refer an eBook in iBooks via a URL?
I have some eBooks in ePub format on my iPad Air 2. But I need to classify them into different categories in some logic. So I wanna create a holding -eBook for each category, and it only has a Table of Contents (ToC), which offers links to some ePub files. I know how to create or edit ToC (basically a html file), and how to create a URL for webpages or another html file (say for one chapter) within the same eBook, but I don’t know what hyperlink (URL) should be used for an outside ePub file but in the App iBooks.
Your help is highly appreciated.
