Due to the evolving nature of the winter storm predictions and a travel ban issued for New York City through noon February 23, 2026, we are making further adjustments to hours of operation at all library locations for tomorrow, Monday, February 23. Please check library hours before visiting.  

• All Morningside Columbia library locations and service points will close at 5:00 p.m. today, Sunday, February 22, 2026, except for Butler Library, which will remain open as a 24-hour study hall. 
• There will be no deliveries of Offsite materials Monday, February 23, 2026. 
• Please check library hours before visiting.

• Please review the current campus status level to determine your level of access.
  
• Alumni can register for same-day access to the Morningside campus using the online campus registration portal. (Note: Community CUIDs will not provide campus access at this time.)
• Once on campus, alumni can use their Community CUID to access libraries. Alumni who wish to apply for a Community CUID can find instructions here. Alumni with a CUID will still need to complete the registration form ahead of their visit and have a QR code to enter campus.
  
• Please check individual library hours before visiting.
  

The C.V. Starr East Asian Library is temporarily closed for construction.
