There are two easy steps to follow for archiving data with the DDCN:

1) To ensure respondent confidentiality, the depositor needs to remove all information identifying individuals that have participated in the study.

The depositor should fax to DDCN (+1.734.763.5850) a signed Data Deposit Form.

Sending the Data

1)  Files with less than 5MB in size can be sent by email. You may submit data sets and their documentation to us via email at DDCN@bus.umich.edu.  

2)  FTP transfers can be quickly arranged at the depositor's request.  

3)  For mailing CD's, diskettes, or hardcopies of documentation, our postal address is:
