This study targets librarians and information professionals who use Web 2.0 tools and applications with a view to providing snapshots on how Web 2.0 technologies are used. It also aims to identify values and impact that such tools have exerted on libraries and their services, as well as to detect various issues associated with the implementation of Web 2.0 applications in libraries. Offering Web 2.0 tools and technologies to library patrons is also suggested. (Contains 5 figures and 1 table.)
