Accessibility of research data to disabled users has received scant attention in literature and practice. In this presentation, we briefly survey the current state of accessibility for research data and suggest some first steps that repositories should take to make their holdings more accessible. We then describe in-depth how those steps were implemented at the Qualitative Data Repository (QDR), a domain repository for qualitative social-science data. We discuss accessibility testing and improvements on the repository and its underlying software, changes to the curation process to improve accessibility, as well as efforts to retroactively improve the accessibility of existing collections. We conclude by describing key lessons learned during this process as well as next steps.
