Don Foster was asked to track down Ted Kaczynski by studying the Unabomber's own words (and uncovering fresh information about his choice of victims). Foster, a Vassar prof who solved a centuries old mystery involving a Shakespearean sonnet and unmasked the anonymous author of a sensational Clinton campaign book, has written a book about science, words and identity. You can run and hide, he says, but your words will always give you away. Author Unknown is relevant to life online, where responsibility for words and anonymous authorship is an everyday issue. http://slashdot.org/books/00/12/26/2038233.shtml
