You missed the last lecture
If your library has a waiting list for the book "The Last Lecture" by Randy Pausch it will probably be getting longer. The first print run of the book has run out. Both Barnes and Nobles and Amazon are out of the book. Amazon says that the book is expected to be in stock again on May 7, 2008. In case you don't know the back story on this book here is an ABC news story about it. And here is the lecture that started it all.
