Robert Sharoff and William Zbaren, architectural writer and photographer, respectively, were in Detroit two years ago to do a story on the Book Cadillac Hotel; they fell in love with Detroit 's buildings and decided to do a book on Detroit 's architecture. The result of their collective swoon is a book that's come out just in time for the holidays. The handsome new coffee-table book from the Wayne State University Press, " American City : Detroit Architecture 1845-2005," was a labor-intensive labor of love. Color photos that accompany the story are attributed to the Wayne State University Press.
