Purpose - This article seeks to propose a new vision for public libraries in the digital age. Design/methodology/approach - This conceptual paper is based on an understanding of the recent developments in ICT, internet and digital libraries; and also on the authors' personal experience in research and development in library and information science - especially in relation to public libraries - and digital libraries. Findings - The study argues that currently there are no proper mechanisms for capturing, preserving and disseminating community knowledge,and proposes that public libraries in the digital age should take a new role whereby they should act not only as a gateway to knowledge, but also as a platform facilitating the creation of, and access to, local community knowledge. Proposes a model for PL2.0 where public libraries can take on this new role to build a network of community knowledge. Research limitations/implications - The paper proposes a conceptual model for the second generation of public libraries, and further studies are required to test and implement the model. Practical implications - The paper proposes that the new role of public libraries will be to shift from solely providing access to knowledge to acting as a platform for the storage and dissemination of local community knowledge within the global context created by twenty-first century digital technologies. Originality/value - The proposed model will bring in a "cultural change" by giving a new role to public libraries in preserving and disseminating community knowledge.
