Reused Elements in JKM LibGuides

This is a safe home for all boxes and pages that appear in several guides, so that the original element is not deleted accidentally and so the element can be updated for every guide with one edit.

Constructing a Search with a PICO Question

Use Boolean operators to join your search terms. Here's how they work.
AND limits results and returns all of the terms joined with AND  falls AND long term care
OR expands results, returns either word, use with synonymous terms. best used in conjunction with an AND search sensory processing AND teenagers OR  adolescents 
NOT excludes terms from search dolphins NOT Miami

 

Keyword vs. Subject Searching

While thinking of related terms and concepts is useful in searching, some databases, like CINAHL and MEDLINE, also utilize subject headings.  Knowing the difference between them and when to use a keyword vs. a subject heading can have an impact on your search results.

Keywords
Subject Headings
Looks for word occurrence in multiple locations of results Only searches the subject headings field of results
Is a broader search and will yield more results, not all of them relevant Is more precise, and yields less, although more relevant results
You can "make up" a keyword Subject headings are chosen from a preexisting list and cannot be altered
