class this is a simple solution.
Lets say that a student has created a book but you don't want to publish it to the iBooks store. However, you do want to make this book available to other students - to download, share and read it.
- Export the book as an iBook from the Share menu in iBooks Author and the finished book will have the .ibook file extension.
- Next, upload this copy to Dropbox and share the link with your students.
- Place the file into the Public folder in Dropbox, this takes less clicks to download.
- Finally, students need to visit the Dropbox site in Safari on their iPads and click the option to open the file in iBooks.
- All students now have access to the finished book and can read it in iBooks on their own iPad.
