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](https://archive.org/web/) 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.
