What is the difference between PubMed and MEDLINE?
In this article, we will explore the differences between PubMed and MEDLINE, including their coverage and usage in literature searches.
PubMed is a free online search engine that gives you access to one of the world's largest biomedical literature libraries, the MEDLINE database. PubMed, which is maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH), has become a must-have resource for researchers, clinicians, and students in various healthcare and life science domains.
PubMed allows users to browse a vast database of citations and abstracts from peer-reviewed publications in subjects such as medicine, nursing, dentistry, veterinary medicine, and the health care system. PubMed's database contains over 30 million citations, making it a go-to resource for accessing the most recent breakthroughs and research discoveries in biomedical sciences.
Content Type | Coverage |
|---|---|
Journals Indexed | Over 5,000 biomedical journals |
Subject Areas | Medicine, nursing, dentistry, veterinary medicine, health care system, and preclinical sciences |
Publication Types | Journal articles, books, book chapters, reports, and more |
Date Range | Citations from 1966 to the present |
Enter keywords, author names, journal titles, or other relevant metadata in the search bar.
Use Boolean operators (AND, OR, NOT) to combine search terms and refine the results.
Access the advanced search interface to utilize more specific search fields, such as title, abstract, author, and journal.
Browse the MeSH-controlled vocabulary to identify relevant subject headings for your search.
Incorporate MeSH terms into your search queries to improve the precision and relevance of the results.
Save your search queries to retrieve them later or set up email alerts to receive notifications when new articles matching your search criteria are added to the database.
Explore the citation network of a specific article, including citing articles and related studies.
Identify the impact and influence of a particular piece of research within the scientific community.
Export citations in various formats, such as RIS, MEDLINE, and CSV, for use in reference management software.
Share search results and citations with colleagues or collaborators.
MEDLINE, the primary component of PubMed, is a bibliographic database that contains millions of citations and abstracts from over 5,600 biomedical journals published worldwide. These citations are curated and indexed by the NLM, using a controlled vocabulary called Medical Subject Headings (MeSH) to ensure consistent and accurate representation of the content.
Content Type | Coverage |
|---|---|
Journals Indexed | Over 5,600 biomedical journals |
Subject Areas | Clinical and experimental medicine, public health, nursing, dentistry, veterinary medicine, and preclinical sciences |
Publication Types | Journal articles, letters, editorials, and more |
Date Range | Citations from 1946 to the present |
The search process in MEDLINE is similar to PubMed, as MEDLINE is the primary database that PubMed provides access to. However, some key differences include:
MEDLINE can be accessed through the OVID platform or the NLM's interface (available on the PubMed website).
The search interfaces may differ slightly in their functionality and presentation.
OVID MEDLINE offers more advanced search options and field-specific searches compared to the PubMed interface.
Users can leverage OVID's powerful search syntax and command-line options for more complex queries.
MEDLINE uses its controlled vocabulary, called MeSH (Medical Subject Headings), for indexing and retrieving articles.
Familiarity with the MEDLINE MeSH thesaurus can enhance the effectiveness of your searches.
While PubMed provides access to abstracts and citations, MEDLINE users may need to access the full-text articles through their institutional subscriptions or interlibrary loan services.
