How do you close a book and stop a split screne

Hi Alan - and welcome to the forums.

You don't really close a book in the iPad app - you just open new ones!

What, specifically, are you wanting to do?

You also mention split screens in your subject field. To remove them you drag the semi-circle at the bottom of the screen to the right of the screen.

Hope this helps - if not, please post back

Excellent - enjoy
