Meeting the needs of learners of all abilities

Page Updated 4/28/2022

A Long-Standing Commitment

For nearly two decades, VitalSource has worked to ensure our products are designed from the beginning with accessibility in mind. We go beyond simply adhering to industry standards, as we are also actively involved in helping create those standards through participation in and leadership with key accessibility partners.

Active in the Community

VitalSource works with organizations such as the W3C, DIAGRAM Center, Book Industry Study Group, the Center for Accessible Materials Innovation, and the EDUPUB Alliance (EPUB for Education). We also collaborate with consultants and advocacy groups, such as the National Federation of the Blind, JISC, Tech for All, and others to grow the community and the capabilities of each part of the system.

Sustained Transparency

Solving the needs of learners requires a great deal of collaboration and accountability. VitalSource demonstrates its Section 508 compliance by publishing the VPATs for its products. But our commitment goes beyond mere compliance—we are transparent about our capabilities because learners and partners need to know how we meet their needs.

Supporting All Users

At VitalSource, we believe that every user should be fully supported for every title they use. This is why we ensure we conform to level AA of the Web Content Accessibility Guideline.
