Enhancing accessibility of e-Books (EPUB)

Table of Contents


  • Digital books are essential teaching and learning resources. Researchers may publish books to disseminate their research findings. Scholars may publish professional and academic textbooks.
  • It is common to create separate versions of the publications which address certain specific needs of certain groups of potential users as a kind of reactive practice. However, it would be great to create a single version of the publications that could cater for the diverse needs of a wider range of groups of potential users (i.e., “born accessible”) at the outset.
  • Some digital books require specific reading devices or programmes for reading. It is essential to consider the accessibility of both the book formats and the reading devices or programmes.
  • It is important to consider accessibility from the beginning of the publication process to better cater for the diverse needs of the potential users to the greatest extent possible.
  • In this section, there are some generic and useful resources about creating accessible publications. These resources are not exhaustive or definitive.
