Document Delivery and Interlibrary Loan are our services to obtain items that are not available in the Columbia University Libraries. This service is for Columbia Affiliates Only.

Lamont campus patrons should contact the Geoscience library staff in Lamont Hall by e-mail or phone (845-365-8808) to request materials not available in the Geoscience Library. When requesting material be sure to include as complete of a citation/reference as possible (author, title, volume, pages, etc).

All other Columbia University affiliates should contact the Interlibrary Loan Office directly.

There is no charge for this service. However, since the libraries bear all the cost, please limit your requests to the ones you need.
