8.5 x 11 softcover

11x8.5 softcover books are available as a binding option

I'm just wondering why in the photo book products page: http://www.prestophoto.com/wiki/Catalog , there is the option of the 11" x 8.5" perfect bound soft cover book, but on this page it explains that "11"x8.5" Landscape Photo Book available in Imagewrap Hardcover, Die-cut Hardcover, and Wire-O Calendar bindings." Are the softcover 11"x8.5" photobooks available?

Thanks,
Adam
