On the Edit Collection page, you’ll see four options for editing your collection: General Settings, Collection Description, Resource Description, and Access Policies.
On the General Settings tab, you can edit the basic collection information you entered when you created the collection through the Collections page (or add this information if you created the collection through Imports).
On the Collection Description tab, you can add additional metadata about your collection. Click on the Sort Collection Fields button to drag and drop fields to display this information in your desired order on the collection’s webpage. Click “Add More” to add multiple values for any field.
