A monograph is a detailed written study or scholarly work that focuses on a specific subject or topic. It is typically authored by a single writer and provides an in-depth analysis, research findings, or a comprehensive overview of the chosen theme. Monographs are often published as books or reports and are used in academic and professional settings to contribute to knowledge in a particular field. These works are distinct from textbooks or anthologies, as they concentrate on a singular topic rather than covering multiple subjects. Monographs are commonly found in various disciplines, including history, science, and literature, and serve as valuable resources for researchers, students, and professionals seeking specialized information.
