PubMed is made available from the National Library of Medicine and includes the MEDLINE index of biomedical and health sciences literature, including nursing. It provides over 27 million citations.
Although PubMed is a free database, always be sure to access it via the designated PubMed @ UToledo link (on or off-campus) which will allow you to connect to full-text articles from e-journals subscribed to by the UToledo Libraries.
In addition to keyword and subject heading searching (see Step 2: Perform Your Search), PubMed also offers a specialized Clinical Queries search tool to find high quality evidence, including systematic reviews and individual research studies according to clinical study category (etiology, therapy, diagnosis, prognosis).
To conduct a clinical queries search, click the Clinical Queries link under PubMed Tools on the homepage.
PubMed provides several options for searching. The two most common search methods to find articles on a topic are 1) keyword and 2) subject heading (MeSH) searching.
Keyword searching is a recommended way to begin your search. New articles (epub/ahead-of-print) that have not yet been indexed with subject headings can only be found by doing a keyword search. Therefore, keyword searching is essential to ensure a comprehensive search. PubMed will retrieve articles based on the keywords that you entered, and will also "map" those keywords to the relevant Medical Subject Headings (MeSH). View a video tutorial here.
Medical Subject Heading (MeSH) searching is a targeted way to search PubMed and will retrieve articles indexed in MEDLINE. MeSH is a controlled vocabulary. It functions much like a thesaurus, so if there is more than one way of describing a topic, the MeSH term will take all those varieties into consideration (i.e. the MeSH term Myocardial Infarction will find articles that use the term heart attack).

After your retrieve your search results, various limits and filters to narrow down your results will appear on the left and right side of the page, including Publication Dates, Article Types, Nursing Journals, and more. To view additional options for filtering your results, click the Show Additional Filters option on the left side of the page.
While you search, PubMed keeps track of your search terms, including keywords, subject headings, and any limits applied, as well as the number of results retrieved for each search. To access your search history, click the Advanced link located above your search results.
