Wrong pub date?

I've noticed the original publication date is listed as 2000, but I think it should be 2007. All but one edition is listed as 2007, and the original copyright date in my copy is 2007. The edition with the 2000 pub date doesn't have any cover picture so I'm wondering if it was a typo.

WorldCat confirms 2007.

I can't find anything anywhere on the web that says 2000. Everywhere says 2007.
