DIAGRAM Project Partners

Benetech, NCAM and the U.S. Fund for DAISY lead technology initiatives that fundamentally change how people with print disabilities experience and interact with different forms of media, from the DAISY and EPUB 3 Standards to the Bookshare library to NCAM’s work on image descriptions.

The main goal of the DIAGRAM Project is to make it easier, cheaper, and faster to create and use accessible digital images.


  • Diagrammar: A Framework for Making Images and Graphics Accessible
  • May 2016: DIAGRAM Center Image Guidelines for EPUB 3
  • July 2015: New Expanded Image Description Guidelines


    • Fewer than 10% of books are available in accessible format.
    • The burden of accessible image preparation typically falls on educators who have limited time and tools to create useful descriptions or accessible graphics.
    • Barriers to accessing information pose fundamental challenges for students with print disabilities.
    • Students using text-based accessible instructional materials are presented with only the words “image” or “graphic” when using software devices that encounter illustrations, equations, graphics, photos or diagrams in digital textbooks.
    • Numerous studies cite how students with disabilities benefit from digital resources that offer flexible, multi-modal methods of interacting with content.

    DIAGRAM's Mission

    • develop simple and cost-effective tools and best practices for producers of accessible instructional materials, such as publishers and state and local education agencies
    • expand the field of image description and interactive exploration of graphical content
    • increase the understanding of accessible image production and access strategies
    • create open source tools to make graphic content more accessible and widely available
    • make a broad range of general education curriculum accessible and graphically understandable
    • accelerate the development and inclusion of accessibility specifications for high-quality images in electronic publishing standards to support implementation by technology developers
    • advance national efforts toward providing more equality of access to benefit people with print disabilities.
