Final answer:
When reproducing copyrighted material in a presentation aid, it should be cited properly, including information such as the author and title. Open-source textbooks like those from OpenStax require an attribution on every page. These citations ensure compliance with copyright laws and give credit to the original creators.
Step-by-step explanation:
A presentation aid that reproduces copyrighted material should include the source information and a proper citation. To cite the source correctly, you might need to include elements such as the author, the title of source, the title of container, other contributors, version, number, publisher, publication date, and the location. For instance, if you are using an image from a textbook that is freely accessible online, such attribution might appear as "Image by [Creator's Name], from 'Title of Source', hosted by [Platform], licensed under [License], available at [URL or Physical Location]." When using material from a textbook, such as one provided by OpenStax, you must include an attribution like "Access for free at openstax.org." on every page where the material is used.
