The theme “Libraries: dialogue for change” invites the Library and Information Science international community to discuss, re-examine, re-think and re-interpret the role of libraries as promoters of change. Dialogue is the utmost expression of democracy, the basis for the freedom of expression and information and thus, the gear for a better future. Libraries serve as open, free, democratic, inclusive and participatory meeting places and mediators between knowledge and people. In an era of rapid changes in the socio-economic-technological sphere, libraries ought to define their role as information providers, promoters of reading, settlers for the community they serve, key players in innovation, and leading actors for changes in the society. Libraries and society need to be in a constant, open dialectic relationship. This will lead to well-informed citizens facilitating progress and development, implementing the UN Agenda for Sustainable Development and leading to prosperity in all fields of the democratic society.
