In the “Import an IIIF Manifest or Collection” section, enter the URL for a manifest and click Import.
This will bring up the manifest page
In the “Select a collection to import into” drop down box, choose a collection for the manifest to be imported into. The options are using an existing collection; creating a collection using the current manifest information (if it doesn’t already exist); or creating a new collection with a different name. Creating a new collection will bring up the “Create collection” window.
Click Import Manifest, which will bring you to the imported work.
