This document provides an overview of conducting a literature review for research in architectural engineering. It discusses that a literature review surveys various sources to produce more lasting and widely useful knowledge, and should be done throughout the research process, not just at the beginning. The document outlines that a literature review summarizes existing information on a specific topic and places it in the broader context of relevant literature. It also compares a literature review to an annotated bibliography, and discusses the uses of a literature review in identifying a research question, focusing the topic, understanding ideas and the current conceptual landscape. Finally, it provides guidance on finding resources, developing an organizing and retrieval system, and taking effective notes.
