Disability studies is highly interdisciplinary, and few databases center solely on disability studies. It may make sense to explore other LibGuides related to sociology, biology, gender and sexuality studies, and other topics of intersection. While there isn't a single periodical index, it's also recommended to peruse the disability studies journals listed above.
