Literature Review Types

A literature review can be categorized into several types based on its purpose. A **systematic review** thoroughly collects and analyzes all relevant studies on a topic, providing a comprehensive overview. A **narrative review** offers a broad summary and synthesis of existing literature, often highlighting themes or trends. An **integrative review** combines findings from different research methods to develop new insights. A **state-of-the-art review** examines the latest developments in a field. Lastly, a **scoping review** maps out the extent and nature of research on a topic, identifying gaps and future directions. Each type serves a specific purpose in understanding existing knowledge.
