EDP Sciences is committed to making our websites easily accessible for everyone, regardless of ability and technology. We are continually working to improve the accessibility and the usability of our websites for all users.


EDP Sciences strives to follow the Web Content Accessibility Guidelines 2.1 (WGAC 2.1 level AA) and the W3C standards for HTML, CSS and JavaScript, ensuring compatibility with current browsers and devices and adaptability to user needs, preferences and technologies.

Formats and accessibility

HTML pages are optimized for modern browsers and devices with a responsive design. The content in PDF is available without Digital Right Management (DRM) and can be opened with all PDF readers. HTML and epub formats are structured through conversion from XML JATS (Journal Article Tag Suite) to maximise accessibility. Tables contain captions, header cells and data cells. The language of each page is most of the time defined, ensuring easy conversion to other languages.

You should be able :

  • change fonts, colors and contrast
  • zoom in, without loss of content or fonctionnality
  • use text to speech tools // use speech synthesis tools


However some areas do not fully conform to the WCAG 2.1 standard (level AA). Some of our content in PDF has not been designed for accessibility, notably the older archive content reproduced in PDF format from original printed sources with OCR (optical character recognition), but not totally readable by alternate softwares. Some images within the HTML format content do not have alt tags but most include adjacent legends.
