Resources for Finding Nursing Research

When to Use Google Scholar

Google Scholar can be a useful search tool, because you can search the full text of articles. Use it for these purposes:

  • Locate articles when you feel stuck
  • Identify a useful article, and bring it back to Clark Library databases to see how they describe it
    • You might find the database subject terms, to help you find similar articles.
  • Bring an article to Google Scholar from Clark Library databases, to find newer articles that cite it.
    • Search within citing articles to make sure the newer articles are relevant.

Age Limiters in Library Databases

Some of the databases frequently used by NRS students have special limiters for different age groups; using these limiters is a great way to find articles about your specific population. Limiters can be items you select from a list (default) or text you enter in a search box (noted below).
