The Library has transitioned from the use of the barcode to the CUNY Login for off-campus access to databases. (It's the same login used for Blackboard and CUNYfirst.)
Beginning on August 3, 2020, you will have to use your CUNY Login to access electronic databases from off-campus, if you have not connected through VPN. You already use the CUNY Login to access Blackboard and CUNYfirst.
The barcode will still be used to borrow materials from the Library.
