Like it or not, the world is becoming paperless. Email killed snail-mail years ago, e-books are slowly eroding the demand for paperbacks (though the ridiculously high prices of e-books are slowing that change), and like it or not, court opinions are moving wholly online as well.
Yep, the courts are catching up to WestLaw. After all, who uses hardback reporters anyway? My volumes of Supreme Court Lawyers' Edition are about 15 years out-of-date and only exist to make me look smart (and compliment my office motif).
