What does "hidden" mean:
From EBSCO customer service repm Samuel Neduru (Oct 2020):
"When an item is "Hidden" in Holdings Management, it is excluded from the Holdings Management MARC generation process. However, if you previously received records for these items when they were not hidden, once the resources are then hidden, one-time delete records will be generated - and then no records for the resources moving forward.
In general, when an item is "Hidden" in Holdings Management, it means that it does not appear in Publication Finder, and cannot be referenced by the Full Text Finder link resolver as an available resource to link to - for example, if you find a bibliographic record for an eBook that you have available through the EBSCO eBooks package, the link resolver won't recognize it as part of your full text collection for linking too. Hiding is really quite similar to fully "De-Selecting," but with the main difference being that de-selecting removes all link assignments, notes, proxy assignments, etc. (whereas "hiding" preserves those customizations, making it easier to re-enable the resource at a later date).
If you want eBooks to remain discoverable via Publication Finder and the Full Text Finder link resolver, you would want to unhide the titles."
