$books["978-0743261690"] = "Gilgamesh";
$books["978-0060931957"] = "The Odyssey";
$books["978-0192840509"] = "Aesop's Fables";
$books["978-0520227040"] = "Mahabharta";
$books["978-0393320978"] = "Beowulf";

          <li><?php echo $book ." " .$isbn ; ?></li>

At present, as in for an example, it is outputting as Gilgamesh 978-0743261690, at the closure of the challenge 1,

You just have to wrap the $isbn in parenthesis and you're good to go!
