You might enjoy this book.
This effort represents the culmination of almost twenty years of research by the author that summarizes an estimated 250 thousand man-hours of study of the Shroud over the past twenty-five years by many individuals. This linen is absolutely unique. There is no other naturally occurring linen like it nor does anyone know how to fabricate it. While you may or may not agree with the author's theory of how the image was formed, after finishing this book, you most certainly will known why this cloth holds such fascination for so many.
There are several excellent web sites on the shroud. My favorite is Shroud Story, which provides a wealth of independent scientific data. The other, is Shroud of Turin - Official Web Site.
