Why doesn't my ID work to get into Wolbach?

24-hour access via ID card is linked to building access, which is linked to the CfA staff database. All CfA affiliates who have a current entry in the CfA Staff Database are eligible for 24-hour access to the Library. If you should have 24-hour building access, but your card does not work on the Library doors, contact the HCO Business Office, B-115, 617-495-7540.
