No, you don't need a library card, but you do need an HCC Student ID Card.
You will find a library barcode number on the back of your student ID card. The barcode number is scanned when you check out books or media from the libraries.
You also need to type the barcode number into the login screen when you renew books, use Encore from off-campus, or log in to your library account for other reasons.
Use the HCC Student ID page for more information.
