There are three ways textbook questions can be added to WebAssign.
Any instructor can enter questions from the textbook that they are using in their class.
The second way is for WebAssign to request permission from the publisher of the textbook to add the questions into WebAssign. With this option, all instructors who adopted the textbook for their classes can access the questions. Instructors can organize a group to code questions and make them available for all teachers to use. WebAssign can help in this collaborative effort. A third way is for WebAssign to provide the service of coding the questions.
