ChangeThis

If you're interested in reading what some famous people (Tom Peters, Joel Spolsky, Jay Conrad Levinson, Seth Godin) have to say about marketing, running companies, creativity, and other stuff, then ChangeThis is a site for you.

ChangeThis is creating a new kind of media. A form of media that uses existing tools (like PDFs, blogs and the web) to challenge the way ideas are created and spread. We're on a mission to spread important ideas and change minds

You can download what they call manifestos (PDF format) from their site for free. I found Guerilla Marketing by Jay Conrad Levinson (author of the best selling marketing book Guerilla Marketing) and some other good stuff as well.
