Guide to Columbia Law Library Services and Policies

A special exhibition celebrating the American Law Institute's 100th anniversary is on display on the second floor of the Law Library through the end of April.

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 and please contact the University ID Center. 

For Columbia University Faculty, Researchers, and Staff: 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 and please contact the University ID Center. 

For Columbia University Students:

Before arrival, you must fill out this form, so that you can show the confirmation email to the Public Safety guard at the building's entrance. If you are signed in to any other non-Columbia Google product, you may have to sign out first in order to fill out the form. If your school does not use LionMail, please email referencedesk@law.columbia.edu to prearrange access.
If for any reason your ID does not grant access through the turnstile, entry to the library will not be permitted, please contact the University ID Center. 

For Columbia University (including Law School) Alumni: Alumni ID cards provide swipe access to Jerome Greene Hall and the Law Library. If you do not already have an Alumni ID card, you may obtain one from the Library Information Office in Butler Library during its hours of operation.

Other interested visitors should email referencedesk@law.columbia to pre-arrange a potential visit.

Westlaw, 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 referencedesk@law.columbia.edu.

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.

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.
