This report reflects the findings of a high-level assessment of Overdrive for its conformance with the W3C Web Content Accessibility Guidelines version 2.1 (WCAG 2.1).
There are very few WCAG 2.1 compliance issues with Overdrive, and the few that are present are programmatic in nature and should be relatively easy to fix. However, creating an accessible platform is a constantly moving goalpost, so it is important to keep in mind that there are continual updates to the WCAG standards that may require more work in the future. Below are the most critical issues to focus on correcting to improve access for all potential users of the system.

Top 3 Issues

  1. Compatibility: The biggest issue facing Overdrive is compatibility of the system with ARIA. These are primarily programmatic issues that aren’t visible on the surface, but that were returned on automatic analysis for each of the pages reviewed. Some of these issues will need manual review by a developer alongside an accessibility professional in order to determine the severity of the issue. For an in-depth guide to ARIA implementation, please see the WAI-ARIA Authoring Best Practices Guide from W3.
  2. Information and Relationships: There are minor issues with the information and relationships of the site, but there are very few of them and they should be very easy to fix.
  3. Color Contrast: Color contrast is not a critical issue for this site, however there are some color combinations that result in the contrast ratio falling below the AA standard of 1:4.5 for normal text. The automatic analysis also had trouble determining if there were contrast issues on certain areas of each page and flagged them for manual review. A cursory analysis suggests that these colors are not creating a contrast issue, but they should be reviewed manually for accuracy.
