As the world becomes more digital, the demands on the accessibility of the materials published on the web also increase. A lack of accessibility on the websites risks limiting the opportunities for those with disabilities to access necessary information from authorities. This goes against Article 21 of the Declaration of Human Rights published in 1948 by the UN, which states the right of the individual to public service. The purpose of this thesis is to study the new Swedish law on accessibility for digital publicservice and how the WCAG 2.1 guidelines are applied in Swedish state museums. State museums, on behalf of the government, are responsible for making their content available to all citizens. In our research, we started from semi-structured interviews that were analysed by theme in order to find common denominators between the various museum authorities. We concluded that there were challenges that made working with accessibility more difficult. The biggest challenge at the present seems to be how the law should be interpreted in the best way as the interpretation can differ greatly depending on who’s doing the interpretation. Web accessibility for the authorities is also a question of resources, as the organizations previously haven’t had this as a priority in budget planning. With the new law, the employees responsible for the publication on the webpages hope that this will be something they can use in the future to justify why the organization needs to invest resources in web accessibility.
