How would Stack Exchange itself be catalogued and archived by libraries?

Would there be a DOI-like system used? Or would something else be used?

Ashley Nunn: This is a very theoretical question - what need would a library have for an archive/catalogue of Stack Exchange?
Shog9: I think you need to expand this a bit. Archiving digital collections such as a Stack Exchange site is an interesting topic, but answering the "how" requires a bit more information on what your goals are for the archive.
Joe: DOIs? hell no (not unless you've got someone minting free DOIs for you)
Paul Wheatley: Surely this is an important question? If the community invests effort in building a valuable resource here, preserving it effectively for the long term (probably via a web archiving approach) would seem a sensible measure *in case* Stack Exchange goes out of business.
Shog9: @Paul: that's what I'm getting at - there are a host of different concerns with a project like this. FWIW, preventing the information from being lost is part of why all posts here are required to be Creative Commons licensed and why we provide regular public archives for graduated sites. If you were planning to take that and making it accessible in some other location, or via some other format, it would make for an interesting question...
Jakob: See this question about archiving threads on internet forums.
