Many databases offer the option to search for "peer-reviewed" journal articles - those are academic articles reviewed by the authors' peers for accuracy during the editing and publishing process.
If you are using a database that does not have this filter option, or if you find an article citation somewhere else, you can check if the article was published in a "peer-reviewed" journal or magazine by using Ulrichsweb. Search for your journal or magazine by title and look for a little black and white striped jersey icon next to its name. 
Use these library databases to find scholarly, peer-reviewed articles on your topic. Refer to the video on the tab 'Global Health Information' for more information on what scholarly articles are.
Before you start entering any search terms, spend a few minutes trying to think of as many relevant terms and combinations of terms as you can. This will help you to avoid getting stuck in a rut with the first terms that come to mind.
If you need help in coming up with terms, you may want to try the "Thesaurus" or "Subject Headings" features in the database you've chosen.
Check out the "Help" or "Search Tips" to learn some of the search features specific to that database. Most databases provide similar features, but the methods may vary. Some common tricks:
Try the databases' Advanced Search feature, which usually gives you the ability to search multiple fields (author, title, keyword, subject, etc) with one search and may offer additional ways to expand or limit your search.
If your first search strategy does not work, try another approach. Remember that you can also get help from the library. Check out the links below.
