Reminder about PanGlobal Login Credentials PanGlobal’s Power Engineering textbooks contain time-sensitive login credentials (a unique username and password printed on the front inside cover of the first book in each series) that provide access to additional online resources and self-assessments. These credentials allow initial access to our Learning Management Systems within three years of the textbook print date. After activation, the online access time frames vary depending on the product and begin after the initial log in. This 3-year access restriction is in place to ensure that the online resources accurately support the textbook content. Bookstores and resellers are reminded not to carry over inventory that exceeds this access time.
