Dunnett's Table of Critical Values

Hi all,

I'm new to the forum, and verrry new to stats. I just love these places, lol. Well, here it goes.

Does anybody have a link to the NIST website, to their Dunnett's table of Critical Values? I don't know if they have one posted or not, but am looking for a validated table. If they don't have one, can someone provide an alternative link?

I've been looking, and found a few tables; all with different critical values. So, I'm hoping to find a credible one.
