The CJNR (formally called the Canadian Journal of Nursing Research) is a peer-reviewed, quarterly journal published by the McGill University School of Nursing. In 2009, the CJNR celebrates its 40th year of publication. With world-wide circulation, the CJNR's primary mandate is to publish original nursing research that develops basic knowledge for the discipline and examines the application of the knowledge in practice. Research related to education and history is also welcomed, as are methodological, theoretical, and review papers that advance nursing science. Letters or commentaries about published articles are encouraged.
