PubMed is a free resource supporting the search and retrieval of biomedical and life sciences literature with the aim of improving health – both globally and personally.
The PubMed database contains more than 30 million citations and abstracts of biomedical literature. It does not include full-text journal articles; however, links to the full text are often present when available from Library Services and from other sources.
PubMed vs Google
PubMed and Google have their own advantages. Google and Google Scholar have a great relevance ranking algorithm; however, Google does not have the ability to perform a targeted search or provide filtering options. PubMed provides the ability to search precisely and with filters.
