Can my data be embargoed until I or my research team finish all our planned analyses?

ICPSR has a delayed-dissemination policy that allows researchers to deposit data earlier in the research process so that they may benefit from the data and documentation preparation services offered by staff. Delayed-dissemination contracts require depositors to commit to a timeline, which is usually two years from deposit to data release. Depositors have access to ICPSR files as soon as they are prepared and need not wait for the public release. They must, however, be willing to commit to the timeline for release.
