Web 2.0 tools are the networking based application tools to establish communication from one device to another. The thesis entitled “Web 2.0, Usage and self-efficacy: A study of Library Science Students and Professional Library Staff at Tribhuvan University Central Library of Nepal”. The research study had four main objectives. One was to investigate library science population and familiarity of concepts towards the Web 2.0 tools. The second objective was to identify the common understanding and attitudes of library science population towards the Web 2.0 tools and technologies. Third one was to identify the library science professionals’ and library science students’ learning mode of Web 2.0 and its usage and adoption. Several literatures written on Web 2.0 tools/ applications, its usage and its application on libraries have been reviewed. Data were collected from two populations: library science professionals at TUCL and library science students of T.U. through questionnaire and face to face interview. The period of data collection was February – March 30, 2016. Descriptive statistics was used to organize, summarize and present the data. All together 25 questionnaires were distributed to the population and the response rate was 100%. The research project was designed to explore the perceptions of library professionals of T.U. towards the usage of Web 2.0 tools and services. It investigated their familiarity with Web 2.0 tools, concepts, services, and usefulness to develop their self- efficacy and also explored the barriers in their usage. The majority of the respondents were female (60%), age group from 21-30 (52%), master degree holders (56%) and from library science students (60%). The study revealed that respondents had general level of understanding and usage of Web 2.0 tools in their field. The respondents (100%) agreed that the application of Web 2.0 tools were helpful to develop their self –efficacy and provide interactive library services. Lack of technical iii knowledge provided by the course content of the library science education of TU Central Department and Information Science for the use of web 2.0 applications is found as a most inhibiting barrier in the library science field. Last, but not least, it has attempt to find the changing trend of usage of Web 2.0 tools of the library science populations. According to the findings, most of the library science populations define the Web 2.0 tools according to their need and capabilities. Most of them (88%) think that Web 2.0 tools are social networking tools. In these sense, the general concepts and perceptions towards Web 2.0 tools are very low. It also found that the majority didn’t use some of the interactive Web 2.0 tools and services. Usage of web 2.0 tools between library science professionals and students are found some how different. Lack of the know-how and technical knowledge could be another reason for the low use of Web 2.0 tools and services in the library science fields. Finally, the recommendation is made that; Library Science Education should integrate the Web 2.0 applications in teaching the IT course. Hands on practice workshops should be organized by the Central Department of Library Science and TUCL. In service training should be organized and Tribhuvan University Departmental Libraries should include the Web 2.0 components on their website.
