Best Project Management books

Stefan from the are doing a survey to figure out which project management books you should read. Feel free to add new books to the list or vote on existing ones. I'm actually quite curious on what the result is going to be. As of now it looks as if the book "Der Termin. Ein Roman über Projektmanagement" by Tom DeMarco would clearly win the race.

Talking about books. We live in the mordern world. Books are somewhat old fashion. Here's an excellent blog post, "The 25 Best Projet Management Blogs". I have known of some and they are really good. I think my Google Reader list will become longer again.
