Purpose This study aims to assess the involvement of Egyptian public libraries in supporting digital citizenship and propose a vision to leverage their role in promoting digital citizenship culture, aligning with Egypt Vision 2030 for sustainable development. Design/methodology/approach A questionnaire was used to sample 21 public library managers in Egypt. The study adopted a descriptive-analytic approach, measuring library readiness infrastructure, strategic planning for digital citizenship support and participation ratings on nine dimensions of digital citizenship as defined by the Ribble model. Findings Results indicated a moderate level of participation overall (average score of 1.72), with high levels in dimensions like digital access and digital literacy but much lower levels in others, particularly digital law and digital health and safety. Library readiness was found to have a positive effect on the level of digital citizenship promotion. Research limitations/implications The small sample size may limit generalizability. Future research should explore best practices for digital citizenship programming in libraries and strategies for overcoming implementation barriers. Practical implications The study underscores the need for Egyptian public libraries to enhance their readiness and participation in promoting digital citizenship. This requires investment in digital resources, staff training, community outreach and collaboration with educational institutions and community partners. Originality/value This study provides insights into the role of public libraries in promoting digital citizenship in the context of a developing country’s national vision. It offers a framework for libraries worldwide to assess and enhance their digital citizenship initiatives.
