That’s **fabulous** , @wesochuck! What does it mean to update OCLC holdings? Not a joke - I _really am_ this clueless about cataloging.

For various reasons OCLC likes to know which titles your library owns. It allows you to show up on [worldshare.org](http://worldshare.org) and if you purchase their [Web Visibility service](https://www.oclc.org/en/web-visibility.html).
There are about 1 million ways to do it, this is just one.
