Permission required: Curate
Under Curate > Standard curation, you'll see the location(s) where each collection is currently published in the "Mapped to" field under "Published standard collections." Learn more about what the "Mapped to" locations mean in Libby.
To see all the collections currently published in each section of your website and Libby (for libraries) or in Sora (for schools), go to Curate > Organize published collections. From here, you can also see the order of collections in that section (and rearrange collections, if you'd like).
