Update- May 4, 2018:
I am still working with EBSCO to delete the 1,632 outdated titles from NC LIVE's permanent Ebooks on EBSCOhost Collection. EBSCO is working on it but hasn't yet completed the process, so these ebooks are likely still showing up in your collections. Once the ebooks are deleted, I will send out another message alerting everyone. It is not necessary anymore to form an exclusion collection to hide these ebooks. Once they are deleted, they will be deleted for everyone. I will also be sending out a MARC record delete file as soon as that becomes available.
