Query: Excellent but out of print book

it's been thirteen years since maximum rpm & seven years since this book but it's still relevant for anyone running RHEL 5 or CentOS 5. if you absolutely need a hard copy version of this book don't hesitate to buy it here. i'm not going to go into the details as to why, the other reviewers have done a great job.if you don't feel like shelling out $60+ for a $20 book just google the book's title, it's been published on the web by the author.
