Lamont Library

Numeric Data Collections


Overview

The focus of the collection is on economic and financial data, public opinion and survey polls, health data, inter-governmental organizations' (IGO) data, U.S. and foreign census data, and statistical compendia from the U.S. and foreign governments. The government and IGO data collections are co-developed with the appropriate subject selectors in Government Documents/Microforms.

The collection also includes subscriptions to comprehensive databases and archives such as the Roper Center for Public Opinion, the Inter-University Consortium for Political and Social Research (ICPSR), National Center for Health Statistics (NCHS), and the Wharton Research Data Service (WRDS) collection of financial databases. (Access to ICPSR and NCHS data is via the IQSS Dataverse Network, the data archive created and maintained by the Harvard-MIT Data Center.)

The Numeric Data Services Dataverse provides access to the Cross National Time Series (Banks data), the ITERATE database, and selected survey data. 

Several micro-level CD-ROM resources are available at the Lamont Library. This collection includes the Panel Study of Income Dynamics (PSID), the International Social Survey Programme, and several criminal justice, violence research, and health data files. The General Social Survey (GSS) and the National Longitudinal Survey of Youth (NLSY) is also available in CD-ROM format, as well as through the IQSS Dataverse. For more information or for assistance using these CD-ROMs, please contact the NDS reference staff.

The data librarians assist users in locating numeric data from the collections of Government Documents/Microforms, the Harvard Map Collection, Harvard-MIT Data Center, IQSS Dataverse Network, Murray Research Archive, ICPSR, Roper Center, U.S. Census Bureau, other libraries at Harvard, and data publishers and archives beyond Harvard.

The data archive (micro-level data) is searchable by keyword, date, and survey organization. The iPOLL database (summary-level data) is searchable by keyword, subject or survey organization and survey sponsor; it provides question and response level data.
