There may be times when you decide that you no longer wish to have a resource on your Bookshelf. Maybe you’ve decided that a resource wasn’t working for students, for example. The good news is you can easily delete any item you no longer wish to have on the Bookshelf.
From your home screen, select Bookshelf.
From My Bookshelf you can now choose the resource or folder you would like to edit by selecting the ellipses button to the right, then Delete.
Otus will ask you to be sure you really want to delete this resource. Select Yes and the item will be removed from your Bookshelf.
Now that item is gone! Be careful, though. Resources you delete from your bookshelf are permanently gone.
