If you're working on a research project with a professor or faculty mentor, they may recommend articles to help you begin your readings of the literature. You can use these as a jumping off point to locate additional sources.
A few suggestions to help your searching:
Before searching, brainstorm some keywords based on your topic. The infographics below can help.
Search systematically and keep track of your search terms; this will help you figure out which search strategies provide the best results.
Save and organize the articles and other sources you wish to set aside for further reading and give your files names that make sense for you, e.g. Smith_2015.pdf (Author last name_publication year.pdf).
