3. What MEDLINE is NOT:

MEDLINE does NOT index books or book chapters.
MEDLINE (by itself) does NOT contain the full text of journal articles.

Why is PubMed/MEDLINE Important?

PubMed/MEDLINE provides people from all over the world with access to citations from biomedical articles. It is the largest database of its kind and therefore, an indispensable tool for clinicians and researchers.
