Source for legal Tieflings and Aasimar

[Mcduff]

So I've been told that Aasimar and Tieflings no longer require a chronicle sheet to create (human ancestry only) but I wasn't able to find the exact reference under the additional resources. I figure sooner or later, someone is going to call me on running a tiefling wizard without the necessary sheet and I'd like to have an official link to back me up. Can anyone recommend one to me?

Or am I misinformed?

It's in the Guide to Organized Play, pg. 7.

You just need to be able to provide the backup in terms of race stats from the relevant Bestiary, Blood of (Angels/Fiends) or Dragon Empire book (for Tengu), or Adv. Race Guide, as any thing from Additional Resources.
