Institutions who want to opt out of consortial indexes need to "uninherit" from the central instance in their account
There's a bug that prevents us from accessing the list of consortial subscriptions. But you can "export active resources" which includes a column on consortial subscriptions.
Currently, all resources in Summon are available when you expand beyond the library's resources.
If there are specific things on the list that you don't want your people to see ever, then uncheck it locally rather than uninherit. Alexander Street Press is a resource that you can't access unless your campus subscribes.
Hathitrust is unchecked because a log of it is subscription and unavailable. Database of Open Access Journals is checked
Changes to activation are picked up on Thursday and indexed over the weekend.
PCI harvests data from SFX to determine which you subscribe to that should be included in initial results.
