Web Accessibility Assessment of ISBN Agencies’ Websites: A 2025 Snapshot

The registration of books to the ISBN agencies (ISBN-As) is mainly done through their corresponding websites. However, due to limitations of web accessibility, persons with disabilities cannot equally access the websites of national ISBN-As. But, fortunately, theWorld WideWeb Consortium (W3C) has developed the Web Content Accessibility Guidelines (WCAG) that websites should conform to in order to become accessible. Despite that, the accessibility of ISBN-As’ websites remain a global concern. This study aims to perform a web accessibility evaluation of ISBN-As worldwide. For that, a group of selected websites is evaluated by using Popetech web accessibility evaluation platform. The Popetech platform can scan, identify, and report issues on a group of websites in asynchronous mode. The findings indicate that most of the selected ISBN-As’ websites do not comply with WCAG 2.2, and improvements are needed. In this sense, this study contributes to global awareness about the need for web accessibility for all.
