One of the main aspects of conducting research is searching and reading previous studies that have been conducted on the topic in order to write your introduction or literature review.   Below is a how-to guide on how to search and access scientific literature using general and specific topic examples. Although this guide uses PubMed as the search database, be advised that there are multiple databases to browse through. Make sure to view our other two posts (A Guide to Getting Started with Online Databases and Databases for Online Research) to get some ideas on other databases you can use to access literature and public data.
