The Search function is available on the Find Data page. ICPSR's search indexes the full documentation of datasets, including descriptions of the variables. Some search tips:
You can also browse data by topic, series, geography, investigator, international data, and more.
Another way to search for datasets is to search by variable using the Social Science Variables Database (SSVD) on the Search/Compare Variables page. This ICPSR database enables users to examine and compare variables and questions across studies or series. Enter a search term or query to search for variables and questions. The SSVD currently has over 5 million variables, representing about 76% of ICPSR's holdings that have quantitative data described in statistical syntax.
What's in There? Searching by Variable at ICPSR will show you alternative ways to search the ICPSR catalogue, how to do variable comparisons, how to use online codebooks, and how to use a crosswalk tool for the American National Election Study and the General Social Survey. (47:04, Closed Captioned)
