ICPSR Data Catalog

An international consortium of more than 750 academic institutions and research organizations, Inter-university Consortium for Political and Social Research (ICPSR) provides leadership and training in data access, curation, and methods of analysis for the social science research community. ICPSR provides all of its metadata records in DDI format. About 75 percent of the holdings also have DDI-compliant variable-level information.

The Dataverse Network

The Dataverse is an open source web application to share, preserve, cite, explore and analyze research data. It facilitates making data available to others, and allows you to replicate others work. Researchers, data authors, publishers, data distributors, and affiliated institutions all receive appropriate credit.

A Dataverse repository hosts multiple dataverses. Each dataverse contains datatset or other dataverses, and each dataset contains descriptive metadata and data files (including documentation and code that accompany the data).


A key part of the CLOSER project is the creation of a Uniform Search Platform allowing users to search the metadata from all of the projects included to find key variables for their research. The metadata will be substantially enhanced and made available in DDI-Lifecycle format.

Australian Social Science Data Archive

This repository, which uses Nesstar, provides online access to approximately 2,000 datasets archived with the Australian Social Science Data Archive between 1975 and the present. Areas covered include economics, demography, politics, sociology, psychology, health, law and education. The facility allows browsing, download and online analysis of data.
