"Playing devil's advocate: Wouldn't linking ebooks with print books be particularly useful? Similarly, linking editions. Admittedly we don't do either of these but for it's been asked for for collection management purposes..."
We would quite like to be able to do this but haven't put significant effort into achieving it because:
1. Most searches that most users perform would retrieve both print and e-version or all editions
2. Nearly all our e-resource records are batch loaded without any cataloguer intervention at the individual record level so we have no way of making this work consistently
3. Unless the links are automatically suppressed when the related resource is withdrawn you can end up with a lot of blind links
Hope this makes some sense.
