LUNA 7.5 introduces Collection Sharing. Using the Sharing tool we’ve created a method that allows LUNA administrators to add public collections from outside sources to their own LUNA instance. If you had public collections added to your LUNA instance that were part of LUNA Commons prior to v7.5, you will need to add these collections again in order for the collections to work.
Here is the list of collections and the IIIF Activity Stream for each that you'll need to add following the instructions for adding shared collections:
