The time has come. As mentioned a few weeks ago, the book formerly known as the art of project management will be going out of print. A revised edition, with a new title, will be out in 2008 (If you want to know why, read the post).
If you’ve been waiting to buy a copy of the book, you should do so soon. Amazon and other retailers already have limited inventory (noted by 5-10 day ship times). The used inventory on amazon and e-bay look good, but I don’t know how out of print status will effect that.
Once the book is out of stock, you’ll have to wait for the new edition, which will be out next year.
