The Library is transitioning from the use of the barcode to the CUNY Login for off-campus access to databases. You can currently use either method on the login screen.
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 probably already use the CUNY Login to access BlackBoard and CUNYfirst.)
The barcode will still be used to borrow materials from the Library.
