However, one has to regard the difference between the content and the bibliographic description. There are the main categories "book", "chapter" and "article" for published research. However, these are simply bibliographic categories with several fields differing in each category. Contrary to this, the distinction between a research paper and a book review is about the content. There could be many more content categories, e.g. scientific monography / popular book / textbook / collection of papers / yearbook, or research paper / review paper / scientific report / letter to the editors / discussion paper / extended abstract / book review etc. All these kinds of papers can be published as journal papers or book chapters. There would be too much categories when describing also the content in the categories. There are other possibilities to describe the content, e.g. in the title or the abstract fields. I use to add "Book review" in the title field, see my list of research or these two examples: https://www.researchgate.net/publication/367020391 and https://www.researchgate.net/publication/351454584.
