Im not going to give you the ENTIRE answer, but I will give you a pretty good start if you wish to figure it out. The foreach loop that is given only has the title of the book as the working variable. If you modify the loop like so:

<?php foreach($books as $isbn => $book) { ?>
            <li><?php echo $book; ?></li>
        <?php } ?>

you can use the isbn or "key" of the array as well
