When there is a review not linked to a publication, display the review on the author's summery bibliography. This is particularly important when the author ahs no titel records to display. See http://www.isfdb.org/wiki/index.php/ISFDB:Help_desk#Delete_Author.3F and http://www.isfdb.org/wiki/index.php/ISFDB:Authors_that_only_exist_due_to_reviews for context.
