Change to DOIs

ICPSR is changing its DOI registration agency to DataCite on/around Monday, December 2, 2013. This means that we will be unable to register *new* DOIs during the first week of December. Existing DOIs will be unaffected. In all likelihood, you may run into some non-functioning DOIs for new/updated studies during the transition, but this will be corrected as soon as we are fully moved over. Our apologies for any inconvenience this may cause.
