Thieving knowledge and other creations is plagiarism. Plagiarism must be controlled to provide security and encouragement to creators on whose creative labours society relies on for progress. The best means is to sensitize and educate people from early childhood against this menace and its devastating consequences. This is an internationally commissioned compilation of articles from some of the most well-known known authorities in the field. Included chapters fall in three broad categories: theory of plagiarism and ways to curb it; attitudes towards plagiarism in different countries and various academic disciplines; and punishment for plagiarism. The aim is to promote an ethical culture, and high standards of integrity and transparency in the conduct of research and publications.
