If you pass the complete list of BookCategories to your template as
"categories":
<dl>
{% for category in categories %}
<dt>{{ category }}</dt>
{% for book in category.book_set.all %}
<dd>{{ book }}</dd>
{% endfor %}
{% endfor %}
</dl>
The .all may or may not be necessary - I don't have any code at hand to
test this :)
If you add related_name="books" to the definition of the category field
in your Books model, you could use {% for book in category.books.all %}
in the inner loop.
