Supplementary materials for: Actually accessible data: An update and a call to action

These are the supplementary materials for the article "Actually Accessible Data: An Update and a Call to Action." The project contains three files:

1. Colon-Karcher-Goben_Accessibility-of-Popular-Data-Repositories.xlsx shows the results of automated accessibility checks of seven popular data repositories in the United States and Europe. For each repository a search or browse page as well as a typical dataset landing page were selected and checked with two prominent accessibility tools AXE (https://www.deque.com/axe/) and WAVE (https://wave.webaim.org/). Checks were initially performed in Spring 2022. The reported (mostly unchanged) results are from tests on April 25, 2023. They were performed using Firefox 112.0.2 for Windows with both browser add-ons installed, AXE v. 4.6.3, WAVE v. 3.2.
2. Colon-Goben-Karcher_Acessibility-FLOSS-Repositories.xlsx describes the treatment of digital accessibility in the developer-oriented documentation of six popular open-source (data) repository software projects. The project documentation was reviewed by two researchers with a background in open source software (Karcher as well as a graduate assistant at the Qualitative Data Repository) who looked for specific sections on accessibility and also used search terms to identify relevant sections. This document reflects the status as of April 2022.
3. Colon-Goben-Karcher_Search-Strategies.docx Briefly discusses the literature search strategies conducted for relevant literature. Initial searches in Google Scholar and Scopus were performed in March-April 2022. Additional searches in LISTA are from March-April 2023.
