Take one of your Bookshelf tiles and place it on your Study board in a book space of your choice on a shelf of a value equal (or inferior) to the value of the action.
In order to place a Bookshelf tile you must meet the requirement shown in the book space where you want to place it. Bookshelf tiles must be taken from your supply from top to bottom.
You cannot place more than one Bookshelf tile in the same action, that is, you cannot split the value of an action between book spaces. If you do not have any Bookshelf tile left in your supply you cannot perform a Study action.
If you complete a row or column of book spaces you receive its income in Victory Points according to the number indicated by the arrow on that row or column.
