To manage the textbook filters available to instructors when creating lessons and exams, go to Settings, click Textbooks, and then add or remove textbooks as needed. If you use campuses, be sure to select the correct campus from the drop-down list at the top of the page. This option also controls what content is available to students via the Librarypage in the student portal. If you don’t use a textbook, consider adding the SIMnet textbook. That will give your students access to all the default SIMnet learning materials in their Library.
