Your manifest file can contain as many titles as you’d like to create in NetGalley—just a few, or a whole season’s worth.
NetGalley will check each ISBN/title against your ONIX feed. If there is metadata for that title within your ONIX feed, we’ll pull the information in and create a title record in NetGalley. Title records will be created for all titles in that manifest file for which NetGalley has ONIX data.
As soon as NetGalley processes a manifest file, it will be discarded, and you will not see it within 2 hours of uploading to the Deliver Files page.
If there is no ONIX data for an ISBN in your manifest, no title record can be created in NetGalley. You’ll need to re-upload the manifest again, when the ONIX data is updated to include that title. Or, just use the "Create New" button from within your NetGalley account to manually create a title record.
You can upload manifests as often as needed.
