The brief videos and tutorials on this page show how to choose the best keywords, refine a search, and evaluate the information you find. There is also information explaining what a "peer reviewed" article is and teaching you to build more effective searches.
“And”, “Or”, “Not” (Boolean Operators): Use the words to narrow or expand your search results. For Example:
Use an * at the end of a root word to find all variations of that word. For example, child* will search for child, children, childhood, and children's.
Brainstorm words or concepts that are similar in meaning and use those as additional search terms connected by OR. For example:
college students OR undergraduates OR university students
climate change OR global warming OR greenhouse effect
If you find a good resource, look at the “Subject Headings” or “Descriptors” listed and use those as additional search terms.
Bibliographies/References/Works Cited pages are great ways to find additional resources. You can search the library’s Catalogs and/or Databases to find copies of the sources cited in an article or book that was perfectly on topic for you.
What does "peer reviewed" article mean?
Peer review is the process by which articles are selected for publication in academic or scholarly journals. The articles are evaluated for accuracy, proper research methodology, and the correct interpretation and use of data. This review process is done by other experts or researchers in the same field of study who are the authors' peers, and that's how the process got its name. Articles in magazines, also called popular articles, do not undergo this type of review process, although an editor does do basic fact checking and make grammar corrections. Peer reviewed articles are also sometimes called "scholarly articles" or even "journal articles." If your assignment instructions use any of these phrases, the instructor probably wants you to use peer reviewed articles. It is best to clarify directions with your instructor when there is any uncertainty.
How do I know if an article has been peer reviewed?
Most article databases have a checkbox that allows you to limit your search to only journals that include a peer review process. You still need to make sure the item you want to use is an article, however, because peer reviewed journals have other types of information in them besides reviewed articles. For example, they may have a section of reviews of new books that have been published in their field, or they may publish opinion pieces or letters to the editor. None of those go through a peer review process.

If your results list is too large, use the limit menu on the left side of the results list. This menu shows options for how to more narrowly describe the types of information or articles that you want. Some options that are typically available include the publication date, the type of article (magazine, newspaper, journal article?), a more specific topic (female college students rather than college students), and so on.
Not enough articles? Look first for typos or misspellings. If everything is correct, you need to broaden your topic. For example, if you only found 5 articles about Cryptobranchus alleganiensis alleganiensis AND Ohio. Try adjusting the publication dates to accept older articles; remove Ohio from the search; add "Eastern hellbender" with an OR to the species name; or broaden further by searching "endangered salamanders" rather than this specific species.
