Knjižnice grada Zagreba utemeljene su na strateškom promišljanju razvoja i racionalizacije poslovanja narodnih knjižnica u Zagrebu. Prvotna strateška paradigma bila je usredotočena na izgradnju suvremeno organiziranoga kulturnog sustava. Nakon 2007., kada Gradska knjižnica obilježava 100. obljetnicu, KGZ u središte nove paradigme postavlja komunikaciju, vidljivost i dostupnost sustava javnosti. Daljnjim promišljanjem razvoja programa i usluga uključenih u novi strateški plan, KGZ pronalazi poveznice sa strateškim planovima Grada Zagreba i Ministarstva kulture. Prioritet postaje izgradnja nove zgrade Gradske knjižnice, što je ušlo i u ZagrebPlan 2020. U radu će se prikazati ciljevi strateškog plana, aktivnosti i odjek kampanje javnog zagovaranja izgradnje nove Gradske knjižnice u javnosti., Zagreb City Libraries are organized on the basis of strategic thinking and planning the development and management rationalization of public libraries in Zagreb. The original strategic paradigm was focused on the development of a modern, wellorganized cultural network of libraries. After 2007, when the City Library of Zagreb celebrated its 100th anniversary, Zagreb City Libraries have introduced a new paradigm focusing on communication, visibility, and public accessibility of the library network. The further planning and development of the program and services, included in the new strategic plan of the Zagreb City Libraries, establishes connections with strategic plans of both the City of Zagreb and the Ministry of Culture. The construction of the new building of the City Library of Zagreb has become a priority and has entered the document “ZagrebPlan 2020”. This paper presents the goals of the strategic plan as well as the activities and feedback of the public advocacy campaign for building the new City Library.
