Which links should we maintain?

A lot of websites maintains different set of pages and sometimes the links they display for their privacy policy and terms of service are redirection to other pages. For instance, Skype's main privacy policy is at http://www.skype.com/intl/en-us/legal/privacy/general/ But this page will typically be accessed from the footer with the link to http://www.skype.com/go/privacy/

For our purpose of tracking changes and archiving. Which links should we use?

This is an interesting question. The original vision had been to record a link to a URL that would capture the "user experience" of someone looking at the policy documents. But that will probably force us to archive a lot of stuff. Alternatively we could aim for the "low level" URLs that serve the content of each document in an efficient way. I say go for the latter where it looks feasible.
