On some publishers' sites I see an institutional or OpenAthens login option.  Am I able to login to DML journal and book subscriptions this way?

 

If connecting to a publisher site directly, you may be able to select the institutional login/OpenAthens login option and search for  "Georgetown University Medical Center" or "Dahlgren Memorial Library", login with your university credentials and access DML subscribed content.  
 
However, please note this option is not consistently provided across publisher platforms and can sometimes result in an error. If the login path provided on the publisher site results in an error, it is recommended that you either download the Lean Library browser extension and/or access content via the links provided on the DML website as the DML site and Lean Library will always provide the most reliable access to DML subscriptions.
