The procedure for gaining instructor access to former Houghton Mifflin websites has changed recently due to the integration of former Houghton Mifflin websites into Cengage Learning's eResource Single Sign-On. You will no longer be required to request a Passkey for access.

If you already have an Instructor eResource Single Sign-On account, please log in at http://www.cengage.com/login to add your current former Houghton Mifflin text to your account.

If you do not have an account yet, please go to http://www.cengage.com/login and click on Create My Account to begin the process.
