Library 2.0 or library III : returning to leadership

Purpose: This paper aims to present a critical review of "Web 2.0" and "Library 2.0" applications and proposal of a redirection of resources towards semantic web developments. Design/methodology/approach: This paper is based on a historical review of library development and new technology. Findings: The paper finds that acceptance by the public of "Library 2.0" applications has been low and that social networking tools do not contribute to the core mission of libraries. Originality/value: The paper proposes that the concept of a second era of libarianship and the term "Library II" should apply to the revolution in library services that occurred with the development of the MARC format in the 1960s and that librarians should be looking towards "Library III" by developing new linkages with semantic web tools.
