I have to say I am suspicious of schemes like PURL, which for all their good points introduce a single point of failure into, well, everything that uses them. That can't be good. Especially as it's run by the same compary that also runs the often-unavailable OpenURL registry. _/|_ ___________________________________________________________________ /o ) \/ Mike Taylor <[log in to unmask]> http://www.miketaylor.org.uk )_v__/\ "I don't really think that the end can be assessed as of itself, as being the end, because what does the end feel like?
