When you access Library resources from Off-Campus, you will have to sign in to the Library proxy server. The server maaks your home IP address to let the resource know that you are in fact a member of the Downstate Community.
When you click on a link for one of the Library's licensed resources, you will be asked for a user name and password. Your proxy server user name and password are the same as the ones you use to login to your Blackboard or Brightspace account.
