You are a librarian. Hold this over the heads of your support staff and constantly remind them of the social stratification within the library work place. Don't do tasks that are beneath your level. Be sure to have exclusive, closed-door librarian meetings. Always keep your day-to-day tasks and responsibilities shrouded in mystery. You aren't a good librarian unless people wonder what you do all day.
Besides, if the staff don't think you're important, who else will?
