1. Register for a Dewey account using your Yale email address

2. Your account will be upgraded once a Dewey administrator has had time to approve your request. Approval may take up to 48 hours and you’ll receive an email when approval is granted.

Please note: Dewey provides data for academic and non-commercial research purposes only. Users may not use data downloaded from Dewey for any non-academic or commercial endeavor.
