Law Library News

The Law Library will be open 24 hours a day December 5-22 and limited to current Law School affiliates only December 5-23.

Access to the Law Library During Study and Exam Period

During the Law School study and exam period, from December 5 to December 23, access to the Law Library is limited to current Columbia Law School affiliates.

For Columbia Law School Affiliates: Just tap your CUID at the turnstile to enter the Law Library. 
If for any reason your ID does not grant access through the turnstile, entry to the library will not be permitted. You must contact the University ID Center

Other interested visitors (including CU students, faculty, staff, and alumni) who need to use a particular Law Library item must email at least the day before to pre-arrange a visit.


Using Law Library Databases

Westlaw Edge, Lexis+, and Bloomberg Law all use individual usernames and passwords for access. 1Ls and LL.M.s receive instructions for how to set up their accounts at the time of orientation or during the first week of classes. Transfer students or students who need assistance may email

You may access other Law Library databases from the Law Library's Databases and Indexes A-Z webpage or by searching Pegasus for the name of the database. In most cases you will be prompted to log in with your UNI and password for access.

For assistance using or locating material in one of the Law Library databases, you may contact a reference librarian.

Other Columbia University Libraries

Law students are welcome to both study in and use the materials of the other libraries on campus. CLIO, the Columbia University Libraries' catalog, allows you to search for physical materials as well as by article title for articles contained in many of the various databases CUL subscribes to.

For information on the various services provided by the other libraries on campus, how to obtain materials from them, and much more, visit the Columbia University Libraries News webpage.

Law Library reference librarians are available to assist law students with navigating CLIO and the Columbia University Libraries' collections and services, although we may refer you to other subject specialist librarians on campus where appropriate.
