From publisher blurb: Yes, this is a compendium of all of the material found in various Player Paraphernalias for the Witch Hunter (archetypes, base class, hybrid classes, etc.). However, all of the material has been updated for playability. In addition, a couple new archetypes have been added as well as a new cavalier order, and new feats. And in addition to that addition, the magic sub-domains based on magic schools as found in Player Paraphernalia #15is also included and the witch hunter tool-box found in Player Paraphernalia #12.5. So it isn't just a rehash of old material, but a combination and exhaustive update source for all your witch hunting needs.
