CLIO is currently experiencing interruptions in access for some library users. Please note the following: 

• Anyone on campus can use CLIO in a normal manner.
• Current Columbia faculty, students, staff, and alumni who are off campus should use the following link, where UNI authentication will be required: https://resolver.library.columbia.edu/clio 
• Other library users not affiliated with Columbia do not have access to CLIO at this time. 

Thank you for your patience as we work to restore full access for all users. 

• 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.
  

• Library materials may be returned to any open library location or to the return bins outside of Butler Library; please check campus access updates before visiting. 

Most library materials are renewable online via your My Borrowing Account in CLIO. If you are trying to renew items that are non-renewable, such as Borrow Direct, Interlibrary Loan, or Course Reserves materials, please contact circulation@columbia.edu for assistance.

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

The Arthur W. Diamond Law Library will be closed for renovation beginning in May 2024. More information about that renovation can be found on the Law School’s website.
