The changes will provide researchers with more consistency in accessing materials. After a thorough review of feedback and analysis, the Library concluded that establishing consistent core hours would significantly enhance the user experience within key reading rooms. The new schedule will see reading rooms closing one hour earlier than before and the addition of Tuesday evening hours.
