The Diamond Law Library provides two types of fee-based services for non-academic institutions, businesses, private libraries, and individuals desiring access to its collections.
Among those collections are superseded statutes, current and historical treatises, hard-to-find international and foreign materials, and sought-after titles such as the Martindale-Hubbell Law Directories, from 1868 to the present.
The Document Delivery Service is a pay-as-you-go program for firms, nonprofits, and individuals not affiliated with Columbia University. Most Law Library materials can be scanned or copied (within limits of United States copyright law) and sent quickly as PDF attachments via email.
The Subscription Service provides its many New York metropolitan area law firm and corporate members with quick and easy access to the Law Library and to circulating materials from many on-campus libraries. With payment of an annual fee, members receive expedited service, reduced charges and numerous privileges.
