What I do is just write the json data to a .js file and link it in the page you need it in.

Note that you will have to assign that data to a variable:
Your JSON data doesn't look right to me though, but I don't really know.

Ex:

<script type="text/javascript">

var J = {"book":{"title":"JavaScript, the Definitive Guide","publisher":"O'Reilly","author":"David Flanagan","cover":"/images/cover_defguide.jpg","blurb":"Lorem ipsum dolor sit amet, consectetuer adipiscing elit."}};


alert(J['book']['title']);

</script>
