Older version repository?

I am just returning to graphics from a 6 year absence and switching from C4D to Blender due to cost. I have both Hess’s and Simonds’s books. I would like to load up an earlier release of 2.6 than is available from blender so as to match the one used in the books. Is there anyplace where these are available?
Thanks in Advance

There is a link to previous versions on the blender.org download page

Thank you very much
