Study cards: This is another really neat feature, perhaps one of the best. The iBooks app will automatically turn your highlights and notes into study cards. The cards will also include must-lear words from the glossary.

They follow a paper metaphor, complete with a 3D effect (shown in the first image). Their objective is to make these cards feel like actual library cards.

Like real cards, you have a basic concept on the front and expanded notes on the back. Like every other element in the iBooks app, sweeping your finger will go through all of them. You can also flip them around easily, by clicking on the lower corner.

It's a good translation of the real world, a user experience that is both useful and looks elegant. It will also be useful for any kinds of research, if it's available for every book through the iBooks 2 application.

Open a book, select some text, tap, select note...enter a comment, tap to dismiss.

Tap the screen to bring up the main nav along the top, tap the notes icon upper left.

Tap on 'Study Cards' upper left. The 'Study Options' gear icon should appear top left.
