Visit a university library. If you are on or near a larger campus, it likely has more than one library, so first search the school's webpage or ask someone which library has nursing-related materials. Once there, ask a librarian to help you find books or magazines containing research articles. These make complete resources because articles appear in their entirety, which is not always the case in online research.
Search a nursing-related website. Currentnursing.com, for example, contains a wealth of nursing information, quizzes and research articles. Sites like this help by both providing information of their own and directing you to other resources that may be even more helpful.
Check article databases. Universities usually provide their own databases, but a couple of national ones also can be extremely useful. PubMed has over 20 million medicine-related articles and is run by the National Institutes of Health and the U.S. National Library of Medicine. The site is easy to navigate and provides helpful information about all its articles. CINAHL, the Cumulative Index to Nursing and Allied Health Literature, is more specific to nursing. Here you'll find articles written by nurses, for nurses, and very relevant to nursing careers.
