How do you put books on the bookshelf I know you can activate it but that does nothing to put books on it...

Activate it, go to your inventory, then go to books. Select a book and press the drop button (X on Xbox, but I don't know what you're playing on).

Press the left button when your actually in the shelf's inventory, so you exit the shelf's section. when you click on the shelf you start in the shelf' section, like a sub menu. Pressing right or trying to scroll down wont do anything ( it looks a lot like its frozen or glitching ). Hope this helps!
