I found something really fun at
Copia. I’ve gotten free copies of
Pride & Prejudice by Jane Austen from many places, but Copia’s free version has an extra bonus. They had a college professor who specializes in Jane Austen add over 100 notes into the text. The notes only show up when you read it on their ereader, but when you do, the notes show up on the side of the text so you can read them alongside the book. It’s like pop-up video, but for books! I normally read ebooks on my nook, but this one was worth reading through their app.
You can find the book here:
