This introduction differs from others by providing a comprehensive overview of scientific internet research, thoroughly addressing the methodological approach and analysis of results, and systematically considering research using Web 2.0 services. Research is understood as part of the broader process of "Finding - Evaluating - Recording - Staying Updated." Therefore, tools are introduced that go beyond research, allowing users to document their findings (notebooks, social bookmarking services, and reference management), and it discusses how to stay current regarding one's topics and the research process itself. A practical book for practical use: for researchers, for students, and for those already in the profession who want to learn scientific research methods comprehensively and effectively.
