Supplemental materials (sometimes referred to as ancillary materials) are anything that might accompany an open textbook or open course. Common supplemental materials include:

• Presentation slides and lecture notes
• Assignment descriptions
• Flash cards
• Instructor guides
• Study guides
• Test banks
• Case studies
• Rubrics

Not every project will involve the creation of supplemental materials. Some project may focus solely on the creation of supplemental materials for an existing textbook. Try to incorporate the development of supplemental materials into your initial project planning, as this can add time to your project and alter your initial timeline.

Things to Keep in Mind

• File type/format: What file type or format you choose to use will depend on the type of supplemental material you are creating. However, aim to create supplemental materials in files that can be easily edited by others in the future. For example, Word files are easier to edit than PDFs.
• Accessibility: Supplemental resources still need to be accessible. Ensure you follow the guidelines described in the Accessibility chapter. In particular, review the section on “Document Accessibility” for accessibility resources for different file formats.
• Attribution: Ensure you attribute all non-original content (see Citation and Attribution for more information). In addition, make sure that your name and the license for the supplemental material as a whole is put at the beginning of the file (or in a footer) so people know who created the content. It is also a good idea to include a link in the file, directing users back to the primary textbook that this resource supplements.

How Supplemental Materials are Shared

• The file can be uploaded directly to a chapter in Pressbooks, which will allow anyone viewing the webbook to download the file. If necessary, it is possible to keep instructor resources locked.
• The file can be uploaded as a separate file in the Utah Education Network (UEN) digital press with Pressbooks.
