In this presentation I will briefly present the structure of the public library network in the Netherlands, with particular emphasis on the way public library innovation is “organised”. There is currently a community of practice (CoP) organised for every specific area of library innovation which at the same time also addresses officially established national priorities, i.e. lifelong learning, development of traditional library services, education of the young population, etc. Librarians in each of the CoPs share experiences specific to their field based on which they identify future activities aimed at the development of the particular field. Librarians included in this CoP system come from libraries of all types and sizes regardless of the province or region. Keywords: innovation, collaboration, Communities of Practice, network Presented at 11th Croatian Conference on Public Libraries: “Public Library Network – Cooperation in the Development of Digital Services and Public Presentation” http://www.nsk.hr/en/11th-croatian-conference-on-public-libraries/
