Accessibility information (eng)

To make digital products and services accessible to people with disabilities, the European Accessibility Directive was published and widely adopted in 2019. This directive has been converted into Dutch law and will apply to e-books and audiobooks, among other things, from June 28, 2025.

It is therefore necessary that the metadata regarding accessibility is described so that this can be shown by booksellers, libraries, etc. to their users so that they can make the right choice.
