Here are some of the books I have produced through Blurb. The images should provide a preview of the book, tap on the image to turn the pages. The three tiny icons above the book will (a) take you to the Blurb page for the book; (b) do the same thing as (a), it's a shopping cart; and (c) put the preview into full screen mode. The tiny icons below the book change the rendering for softcover, hardcover and possibly dust jacket. This widget is provided by Blurb so I have very little control over it.
