text: Organic Reactions is a peer-reviewed book series that was established in 1942. It publishes detailed descriptions of useful organic reactions. Each article (called a chapter) is an invited review of the primary source material for the given reaction, and is written under tight editorial control, making it a secondary to tertiarylevel source. Each chapter explores the practical and theoretical aspects of the reaction, including its selectivity and reproducibility. The longest chapter runs to 1,303 pages. While individual articles are not open access, the journal's wiki maintains a repository of summaries of reactions. The series is abstracted and indexed in Scopus.
