So the great guys over a Paizo created an Pathfinder Reference Document (PRD). Their PRD through was difficult to mirror because the directory structure was not all relative downward. So here’s their PRD, unaltered except for file locations, in a zip and tar.gz file for easy mirroring.
PathFinder PRD zip Package | Pathfinder PRD tar.gz Package
P.S. And for those who forget how to untar the file do tar -zxvf prd.tar.gz
P.S.S. I’m hosting a mirror here.
