  Accessibility research sits at the junction of several disciplines, drawing
influence from HCI, disability studies, psychology, education, and more. To
characterize the influences and extensions of accessibility research, we
undertake a study of citation trends for accessibility and related HCI
communities. We assess the diversity of venues and fields of study represented
among the referenced and citing papers of 836 accessibility research papers
from ASSETS and CHI, finding that though publications in computer science
dominate these citation relationships, the relative proportion of citations
from papers on psychology and medicine has grown over time. Though ASSETS is a
more niche venue than CHI in terms of citational diversity, both conferences
display standard levels of diversity among their incoming and outgoing
citations when analyzed in the context of 53K papers from 13 accessibility and
HCI conference venues.
