Google calendar resource managers can control who has access to book the resource by sharing the calendar. Here's how:

1. If the calendar does not appear in your list of calendars, Subscribe to your calendar resource
2. Share the calendar, giving See all event details access to those who only need to book the resource 
   

What All the Sharing Levels Mean for Calendar Resources

If resource managers need to give a person different access to the calendar, here's how the sharing permissions work for resource calendars:

1. Make changes AND manage sharing:
   • Allows person to see events on the calendar resource, book it, make changes to events on the calendar resource, and control who has access to book it; this is the access calendar resource managers have
2. Make changes to events:
   • Allows person to see events on the calendar resource, book it, and make changes to events on the calendar resource
3. See all event details: 
   • Allows person to see events on the calendar resource and book it but not make any changes to the events (Give See all event details access to those who only need to book the resource)
4. See only free/busy (hide details):
   • Allows person only to see when the resource is busy and when available but not book it
