Question about link to code library from the playground page

Hi, I stumbled on this page (via a Google search) http://arduino.cc/playground/Code/Code and seems quite useful with example code.

My question is where does it link from? I have visited Arduino Playground - HomePage several times and there seem to be no link from there...

No big deal for me now as I have bookmarked it, but it seems a link from the playground would be logical?
