I think part of the problem with links I sometimes have is when contributors make the title on your blog too long and I can't pick up the entire link.
So maybe your post title should just have the title of the book and author. If I have been missing yours this would apply. The shorter the better for our purposes.
Also if you don't have the book title or author in the title, I can't see them in the link I am picking up.
