It is my hope that from now on, we'll be able to keep this page current, and Worldcons won't have to keep "local" copies of the Official Papers on their own web sites, but will instead be able to point to the WSFS site for the WSFS documents. (The individual convention's site will of course continue to have information about the specifics of that Worldcon's meeting arrangements, but will no longer have to host the rules.) This should lead to WSFS.org being the one-stop-shop for questions about what the organization's rules are. Also, as we find them, we will add documents from past Worldcons and build up the historical archive.
Based on some of the feedback (essentially people wondering why the page wasn't updated the day after Worldcon ended), I anticipate that in the future, as soon as Worldcon is over, the documents from the just-ended year will move to the Archives, and the "Current Year" page will have no documents linked, but will more prominently say something like "The documents as of the end of [Worldcon N/Year] will be published here as soon as they are available."
