It houses essays produced by Columbia students in the Graduate Schools of Journalism. Lehman Library also houses the following collections:
- Digital Social Science Center (DSSC) (East Reading Room)
The DSSC provides a wide range of information and technology assistance for students and faculty. DSSC brings together people, equipment, and information resources, including a Data Service.
- U.S. Government Documents (housed off-site)
The Columbia University Libraries currently receives approximately 50 percent of the items available through the United States Federal Depository Library Program. Print materials are processed for off-site storage, but most titles are available online via CLIO.
- New York State Documents
Lehman Library was a depository for New York State documents from 1983 to 1996. The documents are on microfiche in the Lehman Reference Room, and not cataloged on CLIO. For more information see the New York State Subject Guide.
- Map Collection
(213 International Affairs Building)
The Map Room holds a general map collection covering a wide range of subjects, including geography, geology, economics, and international affairs. The collection houses more than 185,000 maps.
- Post-Soviet Nationalities Collection (housed off-site)
A collection of over 19,500 monographs, extensive periodical literature and numerous newspapers on microfilm, in 56 of the Indo-European, Uralic-Altaic, Transcaucasian, and Palæo-Siberian languages of the former Soviet Union. Collecting began in the early 1960's and has grown steadily since then.
- Rand Corporation Publications
The library was a depository for all the publications of this "think tank," up to 2005. There is a CLIO record for each of the individual series published by Rand (Joint Reports, Rand Notes, Issue Papers, Conference Proceedings etc.), but not for each title within the series. The materials are shelved in the Lehman stacks under call number AS36 .R344 -- AS36 .R35; check the shelves for holdings. Rand publications are now available online via the Rand books and publications database.
Columbia's wireless ethernet network is available in most locations in Lehman Library. Coverage is limited in the stacks. For more information about the campus wireless network and how you can equip your laptop to take advantage of it, please consult the CUIT Wireless Networking website.
