The Columbia University Libraries' hours page. This will display a full yearly calendar of our hours.
Inter Library Loan (ILL) Hours
ILL is open Monday to Friday 9am to 5pm.
Archives and Special Collections Hours
The Archives & Special Collections reading room will close on March 31, 2008 and will remain closed until further notice. Departmental staff will be preparing the collections for the move into temporary space while the old stack areas are demolished and new ones constructed.
Limited reading room access will be possible during this time for Columbia University and New York-Presbyterian Hospital administrators only. Email and phone reference inquiries will still be accepted but response time will be much longer than previously.
Please bear with us during this time of transition. We will try to make this disruption as brief as possible and will work with patrons to find alternative sources for the materials they need.
For further information, please contact us at (212) 305-7931 or hslarchives@ columbia.edu.
