Did you purchase the product online, or was there an access certificate (serial number) packaged with your textbook?

If the product was purchased through an access certificate (serial number), you must first register the serial number before you can enter to use the product.

If the product was bought online (through the ecatalog), you must bookmark it immediately after linking to the start page and always access it though the bookmark. If the bookmark is corrupted or was not created properly, then you can re-authenticate and recreate it.

If you need help with your password see below.

To register an access certificate (serial number):

  • Have your access serial number handy. (You may not share a serial number with anyone else. The serial number provides access for one person for a subscription period. Then you must buy a new one. This can be purchased through the South-Western Catalog.)
  • Click on the Register button.
  • Then click the link at the bottom of the page and follow the prompts.
  • IMPORTANT: When you click on the link at the bottom of the page, you will be asked first to enter your serial number and a new or existing user name. It is extremely important to enter your serial number exactly as it appears on the card. Make sure you type the dashes, pay attention to capitalization, and be certain to distinguish letters from numbers. An "O" with a slash through it is a "zero." The letters "C," "G," and "Q" also are frequently mis-keyed. If you do not enter your serial number exactly as it appears on the card, you will not be able to register properly.

To enter when you have registered your access certificate (serial number):

  • Have your username and password that you created during registration handy. (A copy of this is automatically emailed to you when registration is completed.)
  • Click on the Enter button.
  • Then click on the Enter Here link under "I registered Carbaugh Xtra! via an ACCESS SERIAL NUMBER"
  • Enter the username and password you created when you registered.

How to Reauthenticate (general instructions):

  • Click the Enter button.
  • Click on the Enter Here link under "I purchased Carbaugh Xtra! ONLINE" It will bring up an instructions page.
  • Click the Reauthenticate now! link at the bottom of the instructions page.
  • Enter your Thomson store username and password. This will open up your smart receipt.
  • Click on the order number link for that purchase and you will see the Access Online link.
  • Click on the Access Online link.
  • Then, before clicking on the Access Carbaugh Xtra! button you need to bookmark it. This keeps your subscription information in the link. Once you go past the Access Carbaugh Xtra! button and back up to the start page it will not work correctly. In Netscape, Bookmark this page for future access. In IE, add this page to Favorites.
  • Next time you want to access, use the bookmark you created. Your Bookmark/Favorites link will be called "Carbaugh Xtra!".
  • Then click the Access Carbaugh Xtra! button to enter the product.

For future visits from the same computer:

  • Follow your Bookmark/Favorites link to Carbaugh Xtra!.
  • Click the Access Carbaugh Xtra! button to enter the product. If access is denied, follow the re-authentication procedure.
