CINAHL stands for Cumulative Index to Nursing and Allied Health Literature. You can access CINAHL by clicking on the link above.
CINAHL databases are the most widely-used and respected research tools for nurses, students and allied health professionals around the globe.
CINAHL provides an easy-to-use interface with basic and advanced search features and searchable cited references. CINAHL Subject Headings help users effectively search and retrieve information and follow the structure of the Medical Subject Headings (MeSH) used by the National Library of Medicine (see the next tab for more information on CINAHL Subject Headings).
You don't need to worry about creating an EBSCO account, but the other components of this video are what matter for you -- searching in CINAHL and using CINAHL Subject Headings.
I already know about Google Scholar and PubMed. Why would I want to use CINAHL? Why can't I just Google it?
So in short, when searching on CINAHL, you are much more likely to find what you're looking for and you will not have to search through as much.
