NORC at the University of Chicago is currently collecting data from a number of online resources for the purposes of conducting valuable social science research.  Our non-profit research efforts are aimed at advancing public knowledge of critical social issues and developing insight for informed decisions. If you have reached this page from our robot header, we may be periodically conducting a limited number of data collection operations on your website, and are making every attempt to do so unobtrusively. 

Additionally, a log of our data collection operations on Craigslist can be found here, and our archived data is available upon request. Our archived data is available for access for non-commercial purposes upon requenst, and if you have any questions or concerns, please contact Josh Seeger, Vice President of Technology, at seeger-josh@norc.org.
