Many database companies have created their own tutorials on how to use their resources with wikis, FAQs, short videos, and PDFs:
If you already know the name of the database, you can type it into the search bar on the library homepage or you can click on Databases to see the full list.
When you start your search, use just a few terms.
If you get many results, then add more terms to narrow your results.
Remember: more search terms = fewer results.
Databases differ in appearance, often because they are produced by different companies. However, they also share many features. Note the differences and similarities between JSTOR, Sociology Abstracts (by ProQuest), CINAHL (by Ebsco).
