3. PubMed and PubMed Central (PMC)
PubMed comprises over 22 million citations for biomedical literature
from MEDLINE, life science journals, and online books. PubMed
citations and abstracts include the fields of biomedicine and health,
covering portions of the life sciences, behavioral sciences, chemical
sciences, and bioengineering. PubMed also provides access to
additional relevant web sites and links to the other NCBI molecular
biology resources.
PubMed is a free resource that is developed and maintained by the
National Center for Biotechnology Information (NCBI), at the U.S.
National Library of Medicine (NLM), located at the National Institutes
of Health (NIH).

13. Pros & Cons
Pros
• The articles are from professional or peer-reviewed publications.
•This method can provide the searcher with immediate access to
full-text articles.
Cons
• This search eliminates many important articles found in PubMed.
• Leaves the researcher dependent on a small sampling of
relevant resources. This can be frustrating.
While the list of free full text academic publications found on the
Web and in PMC is growing, the set is small compared to the vast
amount of literature produced.
Consult with a librarian, they can help you find further
resources for your research.
