Data visualization pioneer Edward Tufte has published four books on the art and science of displaying information, including the seminal The Visual Display of Quantitative Information in 1983. To that set, he now adds a fifth book: Seeing with Fresh Eyes: Meaning, Space, Data, Truth. I couldn't find a description of the book, but the website lists the table of contents and shows a few of the page layouts.
His previous four books are some of my favorites about design. You can only order Seeing with Fresh Eyes direct from his site, which says the book is shipping in mid-October. (thx, dewayne)
