Permission required: Curate
If you'd like to remove a published collection from all locations on your OverDrive website, click the Curate tab, check the box next to the collection, and click Delete collection(s).
Or, to only remove a published collection from a specific location on your site, select that location from the left sidebar under the Curate tab.
From there, click the X next to the collection you'd like to remove from that section of your site.
Note: Most collections will be removed from your OverDrive website within a few minutes. However, some may take up to 30 minutes to disappear.
