What is PubMed?
PubMed is a free search engine that accesses MEDLINE, a database of over 36 million citations and abstracts for biomedical literature. It's maintained by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM), which is part of the National Institutes of Health (NIH).
What Makes PubMed Stand Out
- It's a primary source for finding peer-reviewed research articles in medicine and life sciences.
- The interface is straightforward for searching and filtering results.
- It links directly to full-text articles when available, often through the publisher's website or PubMed Central.
Who Should Use PubMed?
Anyone involved in medical research, healthcare, or studying biology and health sciences will find PubMed invaluable. This includes students, doctors, nurses, researchers, and even curious individuals looking for reliable information on health topics.
Is PubMed Free?
Yes, PubMed is entirely free to use. Accessing the database and searching for citations and abstracts costs nothing. While some linked full-text articles might require a subscription from the publisher, many are freely available.
