The Social Science Variables Database (SSVD) was created with funding from the National Science Foundation as part of ICPSR's Infrastructure in the Social Sciences award (SES-9977984). The SSVD is a project to demonstrate the effectiveness of searching across studies at the variable level utilizing the Data Documentation Initiative (DDI) as a codebook markup standard. Codebooks which are marked up according to the DDI standard can be easily imported into the SSVD to be searched without additional processing.
