I am trying to write a critical review based work. For defining some concepts I need to cite a book chapter. And for analysing findings I need to cite three conference papers. Can I use book chapters and conference papers for critical review?
Yes, you can definitely use book chapters and conference papers for a critical review. In fact, it is common practice to use a variety of sources, including books, book chapters, conference papers, and journal articles, to provide a comprehensive understanding of a topic and to critically evaluate the research in the field. It's important to ensure that the sources you use are reliable and relevant to your research question, and that you acknowledge them properly in your work using citation and referencing techniques.
