Initially, this book was developed as a training manual for Cambodian researchers and university students, and it was available in hard copies only in Cambodia. This is the second edition and now is available in ebook format online. We found that this book also can be helpful for more than Cambodian researchers. And it can be in the interest of the general public. Therefore, it is made available in an ebook version, so it is now available online. Thank to whoever is interested in owning a copy. It is believed that users will gain more knowledge about peace studies and research methods through the study of the book and continued practice of field research to gain more practical experiences.
