In December, 2004, Google Inc. announced its collaboration with several prestigious university and public libraries to digitalize their collections and make them available online to researchers. The participating libraries include those at Harvard University, the University of Michigan, Bodleian Library at University of Oxford, Stanford University, and the New York Public Library. OCLC published the 2003 OCLC Environmental Scan: Pattern Recognition report and 2004 Information Format Trends: Contend, Not Containers report respectively. The former report examines the economic, social, research, and technological impacts on libraries, and the latter one lays out the top trends in content and what they may mean for libraries in the next five years. The rapid development of digital and web technology has made a great impact on libraries, which prompts worries about the future of public libraries in Taiwan. This article is mainly to describe the development of international advanced technologies and analyze the situation in Taiwan, and then to give some advice to public libraries for future directions.
