OER Workflow

3. Citing Sources in Textbook

The previously mentioned style of attributions also applies to openly licensed images. The attribution can be included in the image caption, as seen in the examples below, or as a footnote. At College of the Canyons, OER specialists use figure numbers to clearly distinguish each image. The figure numbers are based on the chapter. For example, any image with "5" in the ones place will be an image from chapter 5. An image with "figure 5.7" indicates that it is the seventh image in the fifth chapter of the textbook.

In the first example, the relevant licensing information can be found on the image repository's webpage. While websites like Unsplash, Pxhere, and Pixabay do not explicitly require attribution, all sources in an OER book should be credited. The second example comes from the Wikimedia commons, so the licensing information there will always be associated with Creative Commons or public domain content.
