I would like to archive this so that I can go back to it later, however I can't seem to find the original work and scribd is holding it hostage asking for a signup as ransom. Can anybody point me out to the source?
The original source (Princeton University Press) URL

appears if you mouse over the submission title here. I never read on scribd, which always annoys me with usability issues like that. But, alas, any user of HN who submits a .PDF link will find it automatically styled to also link to scribd.
