Sources for new Skill Options

[Flame Effigy]

New skill options are routinely introduced in splatbooks, but as far as I know, those skill options aren't compiled properly on any website.

Can anyone give me a comprehensive list of what skill options are introduced in what book? Anything related to skills, really.

Thanks in advance.

As far as I know d20pfsrd keeps things pretty updated. I checked Appraise and it had both the Unchained stuff and the bargaining rules (Ultimate Campaign). Sometimes it's hard to find the source but it's generally all there. The biggest problem is trying to tell 3PP apart from Paizo stuff, if you need to make that distinction.
