Mercury Log In Help

You must log in to Mercury in order to access your patron information, to place request, or to be presented with the specific databases that your library allows you to search. If you are not logged in, the Login window will display when you select Log in or any function requiring patron log in.

  • Enter your bar code and your last name in the Barcode and Last Name text boxes. See the Circulation Desk for questions about your patron bar code. Note: Your library may ask for your Social Security # or Institution ID rather than your bar code.
  • Your institution may require a Personal Identification Number (PIN) .
  • After you have entered your bar code and last name, click Log in.
