Borrowing and Renewing for Students
Students may borrow materials from the Law Library for one semester. Some items, however, do not circulate, including:
- items placed on reserve for a course
- primary law sources
- damaged items
- special collections materials
Items may be renewed in person at the Circulation Desk or online by viewing your patron record in Pegasus. For further information about your Law Library account, please contact the Circulation Desk.
Your Law Library books do not appear on your CLIO account; we do not use the same circulation system as the other Columbia University Libraries.
Study Rooms
Study rooms are available on the 2nd and 3rd floor of William and June Warren Hall. They are first come, first served.
Interlibrary Loan for Students
If the Law Library does not have a resource, we can likely acquire it via a loan. Please see the Student Services Guide for information on finding material from Columbia Libraries.
Law students may use and borrow books from any of the other Columbia University Libraries through their online catalog CLIO. Law students can also consult with a Reference Librarian in the Reference Office to borrow materials through Interlibrary Loan from other libraries worldwide. The Law Library participates in OCLC’s sharing service, which makes searching library holdings worldwide available through WorldCat.
Non-law students can contact the Interlibrary Loan office in Butler Library.
Past Exams for Students
Exams given in past years by faculty members currently teaching a course are available in electronic format on the law student network G drive. You can also access this G drive folder through your web browser at http://remote.law.columbia.edu.
Consult the IT Help Desk for further assistance.
Services for Non-Law Students
All Columbia University students are welcome to use Law Library's materials, including borrowing and renewing items. Request books for pick up via our online catalog Pegasus, or by emailing [email protected]. Reference services are available by contacting [email protected] or by visiting WJW 101 during reference hours. Study space is limited to Columbia Law students. Please consult our Guide to Law Library Services and Policies before arriving for access information.
Access to individual Westlaw, Lexis, and Bloomberg Law accounts is restricted to current law students, faculty, and staff. Westlaw Patron Access and Bloomberg terminals are available on the second floor of William and June Warren Hall. These terminals are available on a first come, first served basis and research should be limited to 30 minute sessions.
Computers, Scanners, and Printing
Computers and printers are available on the 3rd and 4th floors of WJW. Book scanners are available on the 2nd floor.
Printing is limited to law students. Troubleshooting and more information is available from the Law School IT department.
The Law Library provides two types of fee-based services for institutions, businesses, private libraries, and individuals who need access to its collections.
For more information, see the Fee-Based Services Guide.
Please use the form below to let us know if there are any books, treatises, DVDs, or other materials you would like placed on course reserves for your Fall 2024 courses.
Once a course reserves request is submitted, library staff will check for available electronic versions of each requested reading. Whenever possible, links will be provided to the Library’s licensed electronic resources. We will also purchase licenses to ebooks that we do not currently have access to whenever they are available for libraries to license as individual titles.
Unfortunately, not all required course readings will have available electronic versions. Some publishers do not offer institutional licenses to all of their ebook content, especially textbooks, and some assigned readings, textbooks, or other materials may not be available electronically through the Law Library. The Library will place print copies of materials that can not be electronically licensed on Course Reserves.
Columbia Law Library Course Reserves Request Form
To complete the form, you should have the name of the course, the course and section number, and the Title/Author/Year/ISBN of any material you wish to have added. Please also indicate how many students are anticipated to register for the course, as the Library will provide a specific number of electronic or print copies based on the number of registered students.
You or your faculty assistant will need to log in using your UNI and password to complete the request form. If you are signed in to any other non-Columbia Google product, you may have to sign out first. This form allows us to process your requests in a timely and efficient fashion, and we appreciate your use of it.
All material placed on course reserves will be removed at the end of the semester. You will be asked again towards the end of the Fall semester for materials needed for Course Reserves in future semesters.
If you have any questions, contact the Head of Public Services, Nam Jin Yoon.

You will need to obtain login and password information from the Reference Librarian on duty for some of the electronic resources.
