Introduction to Literature Review Project

Why Literature Review?

To create more effective accessibility guidelines, W3C Silver Project Taskforce designed both user research and background research. As part of background research, literature/article review and analysis will provide systematic examination about the technical, cultural, and practical aspects of current state of WCAG. Please visit W3C Silver literature review page to see proposed research questions.

What is the Objective?

  • Offer an overview of significant literature published on Web Content Accessibility Guidelines (WCAG)
  • Share what knowledge and ideas have been established on WCAG
  • Find what their strengths and weaknesses of existing researches on WCAG
  • Identify research gap as well as literature outside of accessibility professionals/researchers

How Can You Be Part of the Effort?

We are currently building W3C Silver project group library using Zotero. Please contact JaEun Jemma Ku at to contribute to the WCAG literature review group library (login/invitation required). Invitation will be sent upon request.


What can we learn from WCAG adaptations?

The Web Content Accessibility Guidelines (WCAG) 2.0 were made a W3C recommendation on 11 December 2008. Since that time, individuals and organizations have adapted WCAG in different ways. We believe we can gain insights into what’s needed for the next-generation accessibility guidelines by studying those adaptations—the thinking behind them, the changes made, the effectiveness of the adaptations.

We are particularly interested in:

  • What led up to the decision to create a WCAG adaptation?
  • In the adaptation, what is dropped? What is added?
  • Are there changes to the structure of the guidelines?
  • What content is changed, or reworded, and why?

We welcome input and insights on any aspect of WCAG adaptations that might help us gain deeper understanding into what is needed moving forward. Please share your thoughts in the comments section or via the mailing list.

We are aware there is ongoing research and exploration of WCAG adaptions. If you know of research activities or have been involved in activities yourself, please email JaEun Jemma Ku at Also, please consider contributing to our Literature Review Project.

Discovering Silver Forum

We are launching this Discovering Silver Forum as part of the Silver Community Group website. The Forum is a place to share perspectives about accessibility guidelines and their role in creating inclusive digital environments. We will regularly post topics and invite discussion as comments or via the mailing list.

Our first discussion topic is, What can we learn from WCAG adaptations?

One of the primary goals for the Silver project is to use evidence and data to inform decisions about the next-generation accessibility guidelines. The Silver Design Plan begins at the beginning, with questions about what is needed, and where there are opportunities to push forward using guidelines to support accessibility in the digital environment. In the Discovery Phase, researchers and stakeholders worldwide are working together to find answers to key research questions. From supporting policy and design decisions, teaching and learning about accessibility needs, conducting research and creating standards, and other stakeholder roles and activities, a broad range of perspectives on how accessibility guidelines are used will clarify what is needed to ensure accessibility guidelines are an effective tool for advancing accessibility.

To support work in the Discovery Phase, the Silver Task Force will regularly post research questions as prompts and open the floor for discussion. We will include your comments and perspectives among the research data, which will form the basis for Phase 2 activities of interpreting and synthesizing the data into insights to guide decision-making, as we move from research to concepts.

We look forward to hearing from you!

Welcome to the W3C Silver Community Group

Welcome! Silver is a Task Force and a project of the W3C Accessibility Guidelines Working Group (AGWG). While the main working group is focusing on the Web Content Accessibility Guidelines (WCAG) 2.1 update, a small Task Force is working on the preliminary research for a major update to WCAG. This new update is yet un-named, but it is clear that it will NOT be called WCAG 3.0, because we know that this major update will be applicable beyond just the Web. The name Silver comes from the chemical symbol for silver, “Ag” for Accessibility Guidelines.

Shawn Lauriat (Google) and Jeanne Spellman (The Paciello Group) presented on Silver at the CSUN 2017 Assistive Technology Conference. Their Silver presentation slide deck explaining the project is publicly available.

This W3C Community Group has been set up to support the people outside of the AGWG who are helping with Silver and the Silver research.

Call for Participation in Silver Community Group

The Silver Community Group has been launched:

Support the research and prototyping of the next major version of Web Content Accessibility Guidelines (WCAG).

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

This is a community initiative. This group was originally proposed on 2017-03-02 by Jeanne F Spellman. The following people supported its creation: Jeanne F Spellman, Léonie Watson, Mark Sadecki, Charles McCathie Nevile, Doug Schepers, Greg Lowney, Michael Cooper. W3C’s hosting of this group does not imply endorsement of the activities.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.

We invite you to share news of this new group in social media and other channels.

If you believe that there is an issue with this group that requires the attention of the W3C staff, please email us at

Thank you,
W3C Community Development Team
