Old versions of the OS X Human Interface Guidelines I'm looking to write a paper on how the OS X user interface has evolved from OS X Leopard all the way through to OS X Yosemite and am seeking guidance on where to find older versions of the OS X Human Interface Guidelines documentation.

The following data should aid in the search in the circumstance that navigating the WayBack Machine in the event that that is the only viable option.


OS X 10.5 Leopard Release Date: October 26, 2007
OS X 10.6 Snow Leopard Release Date: August 28, 2009
OS X 10.7 Lion Release Date: July 20, 2011
OS X 10.8 Mountain Lion Release Date: July 25, 2012
OS X 10.9 Mavericks Release Date: October 22, 2013
OS X 10.10 Yosemite Release Date: October 16, 2014


Any help in finding these documents would be greatly appreciated.

If there's not a complete link to them, perhaps several answers could point to each or one answer be maintained to point to them all.
It wasn't easy, but I think I got all of them.
