Dear Stuart,

-- Hopefully not.

One of the questions we try to ask periodically is "how will we deal with X in the future?"  Naturally, it's too early to answer that question in regard to your spelling example, but I entertain thoughts wherein a lot more automation is employed to keep things up-to-date.  Could there not be a reference to the source of *your* Work's description that could be used to look upstream for changes?  Does BIBFRAME enable such a feature (if not, could it)?  What's needed to enable such as use case?  

I also tend to entertain thoughts wherein there is reduced replication of static information (such as titles) that then might lessen the number of descriptions requiring modification when such a mistake is discovered.  In a consortium setting, for example, might there only be one Work resource?   In such a scenario, individual libraries will generate Instance resources, as needed and to be shared throughout the consortium.  Then individual libraries would attach Holding resources to the Instances.

Cordially,
Kevin
