The example books on this page align with the definition of diversity provided by We Need Diverse Books:
"We recognize all diverse experiences, including (but not limited to) LGBTQIA, Native, people of color, gender diversity, people with disabilities*, and ethnic, cultural, and religious minorities.
*We subscribe to a broad definition of disability, which includes but is not limited to physical, sensory, cognitive, intellectual, or developmental disabilities, chronic conditions, and mental illnesses (this may also include addiction). Furthermore, we subscribe to a social model of disability, which presents disability as created by barriers in the social environment, due to lack of equal access, stereotyping, and other forms of marginalization."
