Welcome to H-High-S! The primary purpose of H-High-S is to facilitate an ongoing discussion of curriculum, instructional strategies, and educational resources involved in teaching history, social studies, and related subjects in American secondary schools.
I humbly suggest "Understanding and Teaching U.S. Lesbian, Gay, Bisexual, and Transgender History" (Univ of Wisconsin Press, 2017). Disclosure: I coedit the book series this is a part of, but it is a non-profit press.
You might check out Kim Nielsen's A Disability History of the United States (Beacon Press, 2013).
