This document provides instructions for using the CQ Researcher database to conduct presearch and find a topic for research. It recommends beginning with the "Hot Topics" or "Browse Topics" sections to find an issue that is interesting, significant, and has multiple sides that can be argued. The document cautions against topics that are overused or about which the student knows too much already. It encourages finding a new topic to learn about. An example is given of using the "Pro/Con" section to explore the debate around a carbon tax. Presearch is distinguished from research, and the goals of presearch are outlined as understanding issues, arguments, theories and deciding what further research is needed.
