Sometimes the best solution for your class is using a Low-Cost material. Some publishers offer Low-Cost books, or have created ancillary materials for openly-licensed textbooks available for a small cost. This is only a subset of what is available, so please contact your publisher to see if there are Low-Cost options available for your textbook.
The Library has not evaluated these resources for content nor accessibility. Use your professional and subject expertise in evaluating and using these resources.
Additionally, review the terms of use, copyrights, and cost on any resource you find. All of the above Low-Cost resources are available to students through the University Bookstore.
