How can I find an article published within the last three or five years?
In the Advanced Search screen of databases, you have the option of limiting your search results by year.
In the CINAHL with Full Text database, click on the Advanced Search option and scroll down until you arrive to the "Limit Your Results" section. In the right column, there is the option to select your dates in "Published Date from." You can enter in months and years, or only years.
