When you have a list of stories, for example in search results or the author's page, there's a link with each story description to reviews of that story. When you have an individual story, either on the story info page itself or a More Information link from one's library, there is no link to reviews.
Speaking as a reader, it'd sometimes be nice to get other takes before taking the plunge without having to find the author's page, scroll down, and then finally click through (which seems the easiest path at the moment).
