Your MACKcard is your library card.

• All current, on-campus students, faculty, and staff are issued a MACKcard (Merrimack's ID card).
• If you are on-campus and need a MACKcard, drop by the Tech Bar on the 1st floor of McQuade Library to get one.  
• Your library card number is the 14-digit number on the back of the MACKcard.
• Use this number to check items out, use Libby/OverDrive, and access your library catalog account to renew, place holds, and more.

If you don't have a MACKCard, use your Merrimack Student ID # followed by the letters: "m-e-r" as your Username.
