The copyright law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted material.

Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specific conditions is that the photocopy or reproduction is not to be "used for any purpose other than private study, scholarship, or research." If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of "fair use," that user may be liable for copyright infringement.

This institution reserves the right to refuse to accept a copying order if, in its judgment, fulfillment of the order would involve violation of copyright law.

ILL Services

Interlibrary Loan (ILL) enables eligible Columbia University affiliates to borrow material from other libraries and universities and obtain copies of articles or book chapters from titles that are not owned or available at Columbia University Libraries.

Columbia University Libraries also lends materials to patrons of other libraries through Institutional Borrowing and reciprocal lending arrangements.
