        <item>the ASIN of a book that BookMooch thinks readers of this book might be interested in.  Note that

		they are recalculated when someone visits the book page on BookMooch.  Only books that are moochable at the
		time the recommendations were calculated are recommended. The recommendations are based on a point system,
		looking at what others who have read this book have also mooched, but also what they have/are giving away,
		though books they have/are giving are less important for the algorithm than books they mooched.
		The sort order of the recommendations is relevant: the most recommended books are listed first.</item>
