Many thanks to Gerry and Kirsty for their replies on unstable urls to resources and
their consequences for library catalogue records:

Digital Object Identifier. DOIs can be assigned to
individual articles, and a central database of DOIs and their
associated URLs means that the location of a given article can be
determined reliably by interrogating this database even if the
URL changes for any reason.
Could anyone tell me if a non-subscriber to OCLC or to CatchWord can still use this
technology in order to make a connection from a catalogue record to a journal
article (assuming I have subscribed to the journal and can otherwise access
articles via the web)?
