Description	Bibliographic database for biomedical literature
Access	Public

PubMed is a free search engine maintained by the National Library of Medicine at the National Institutes of Health, providing access to a vast collection of biomedical literature from MEDLINE, Life Sciences Journal Articles, and Online Books. It is widely used by researchers, scientists, and healthcare professionals, including those at Harvard University, Stanford University, and the University of California, Los Angeles. PubMed is an essential tool for finding relevant studies and research papers, such as those published in the Journal of the American Medical Association, The New England Journal of Medicine, and The Lancet, which are often cited by renowned researchers like James Watson, Francis Crick, and Rosalind Franklin.

Introduction

PubMed is an integral part of the National Center for Biotechnology Information (NCBI) and is closely linked to other NCBI resources, including GenBank, Protein Data Bank, and Online Mendelian Inheritance in Man. The database is updated daily and contains over 30 million citations from biomedical literature, making it an indispensable resource for researchers at institutions like Massachusetts Institute of Technology, University of Oxford, and University of Cambridge. PubMed's vast collection includes articles from prominent journals like Nature, Science, and Cell, which often feature research from esteemed scientists like Stephen Hawking, Neil deGrasse Tyson, and Jane Goodall.

History

The development of PubMed began in the 1970s, when the National Library of Medicine launched the MEDLINE database, which was initially available only through mainframe computers at universities and research institutions. The introduction of the Internet and World Wide Web in the 1990s enabled the creation of a web-based interface for MEDLINE, which eventually became PubMed, with significant contributions from organizations like National Science Foundation, Wellcome Trust, and Bill and Melinda Gates Foundation. This transformation allowed researchers from around the world, including those at University of Tokyo, University of Sydney, and University of Toronto, to access the database and conduct searches using a user-friendly interface.

Content

PubMed's content is derived from a variety of sources, including journal articles, conference proceedings, and book chapters, which are carefully selected and indexed by the National Library of Medicine using a rigorous process involving peer review and editorial boards. The database contains citations from over 5,000 biomedical journals, including prominent titles like Journal of Clinical Oncology, American Journal of Human Genetics, and Proceedings of the National Academy of Sciences, which often feature research from renowned institutions like Columbia University, University of Chicago, and Duke University. PubMed also includes links to full-text articles and other resources, such as PubMed Central, which provides free access to open-access journals like PLOS ONE and BMC Biology.

Search_and_Retrieval

PubMed's search engine allows users to query the database using a variety of search terms and filters, including MeSH terms, author names, and publication dates, which can be combined using Boolean operators to create complex searches. The database also provides features like autocomplete and spell checking to help users refine their searches, and tools like My NCBI allow users to save searches and set up alerts for new articles from journals like Journal of the American Chemical Society and Physical Review Letters. Additionally, PubMed provides links to other resources, such as Google Scholar and Microsoft Academic, which can be used to further explore topics and find related research from institutions like California Institute of Technology, University of Michigan, and University of Wisconsin–Madison.

Impact_and_Usage

PubMed has had a significant impact on the field of biomedical research, enabling researchers to quickly and easily locate relevant studies and articles, and facilitating collaboration and knowledge sharing among scientists and healthcare professionals worldwide, including those at World Health Organization, National Institutes of Health, and European Organization for Nuclear Research. The database is widely used by researchers, clinicians, and students at institutions like University of California, Berkeley, University of Illinois at Urbana–Champaign, and Georgia Institute of Technology, and its influence can be seen in the work of prominent researchers like David Baltimore, Elizabeth Blackburn, and Andrew Fire, who have made significant contributions to fields like molecular biology, genetics, and biophysics.

Features_and_Developments

PubMed continues to evolve and improve, with new features and developments being added regularly, such as machine learning-based search algorithms and natural language processing tools, which can help users find relevant articles and identify trends and patterns in the literature, and collaborations with organizations like Allen Institute for Brain Science, Broad Institute, and Sanger Institute to integrate genomic data and other types of biological data into the database. Additionally, PubMed provides links to other resources, such as ClinicalTrials.gov and GenBank, which can be used to find information on clinical trials and genomic sequences, and tools like PubMed Commons allow users to comment on and discuss articles from journals like Journal of Biological Chemistry and Proceedings of the National Academy of Sciences.
