Public Domain Collection
Hi,

My name is Marcela, and I head up one of the Partnership Programs at **Pond5.**  

As part of our library, we host a large **public domain collection** of 80.000+ HD and 4K files available for research and free consumption: http://goo.gl/vr7cM8.

I'd appreciate if you can add our library here.
:)

All the best.
