I agree with this. But I've been thinking lately about what it takes to make a document id persistent for the long term, and have concluded that it requires some prior planning (where do you put it so that it will continue to be accessible) and some committment to providing the necessary resources. Also, sometimes an author knows that a document is going to be revised many times, and thus references to (say) the third chapter of that document aren't likely to be useful for long, because the third chapter will sooner or later be something completely different than it originally was. I'm not sure how best to indicate this, and am interested in seeing others' ideas on the topic. > Most of the "missing link" problems are due to a) the things really becomming > obsolete and b) the initial errors and slopyness of server administrators > and document writers that take their time to realize that they better > had to think twice before deciding on/changing a domain name or the > location and name of a doument. I don't disagree with you, but are you sure? I haven't seen any measurements on it, and this strikes me as the sort of case where one's intuition is likely to be wrong. Are there any studies on why links go bad? Keith
