The PubMed database is a literature database that contains citation information (title, authors, journal, and publication date) and abstracts of articles published in biomedical and scientific journals. PubMed does not contain full-text articles, but in some cases, you can link to full text directly from PubMed.
If you have searched PubMed (or accessed PubMed through a web link) and located a citation of interest, check for full-text icons in the upper right corner of the display above the citation. Some full text articles may be free, for example those archived in the PubMed Central® (PMC) database.
Articles on publishers’ sites may either be free or they may require a fee for access.

If you do not see a web link to full text, contact your local library for access.
