PubMed web version is a free biomedical literature search platform developed by the National Center for Biotechnology Information (NCBI), a subsidiary of the U.S. National Library of Medicine (NLM). It was launched in 1996 and currently contains more than 39 million literature citations and abstracts, covering medicine, life sciences, behavioral sciences and other fields. As one of the most authoritative biomedical databases in the world, its core advantages include real-time updates, cross-database integration, free and open access, and support for full-device access through responsive design, which can be used directly without installing a client.

PubMedpageversionCore functions and features
1. Intelligent search and advanced filtering
Natural language search: Directly enter keywords (such as "heart attack treatment"), and the system will automatically match the medical subject headings (MeSH) and expand the search scope. For example, entering "aspirin" will also search for "acetylsalicylic acid" and its related studies.
Advanced search tools:
Boolean logical operators: support "AND/OR/NOT" combined queries (such as "cancer AND immunotherapy NOT review").
Field limitation: You can specify the search scope as title (ti), author (au), journal (ta), etc., such as "diabetes (ti) AND 2020-2025 (pdat)".
MeSH subject heading search: By standardizing terms (such as “Hypertension” instead of “high blood pressure”) to improve recall and precision, subject headings can be pre-searched in the MeSH database.
Dynamic filtering bar: The left side displays the filtering conditions in real time, including publication time, document type (such as clinical trials, reviews), impact factor range, open access status, etc., and supports one-click filtering.
2. Personalized management and collaboration
My NCBI Account:
Document collection and tags: Create folders to classify documents and add custom tags (such as "Diabetes - latest in 2025").
Search history and strategy preservation: Automatically record search records, support editing and re-running historical queries, or set email reminders (such as pushing newly published "COVID-19 vaccine" research every week).
RSS subscription: Generate RSS links for specific topics and get the latest literature updates in real time through readers (such as Feedly).
Team collaboration: Sharing favorites and search strategies is suitable for scientific research groups to collaborate and manage documents.
Data export and compatibility: Supports export to RIS, BibTeX, CSV and other formats, and is seamlessly integrated into literature management tools such as Zotero and EndNote.
3. Full-text acquisition and open resource integration
Multi-channel full text link:
PubMed Central (PMC): direct link to open access full texts (~10.9 million free full texts) covering more than 780 journals.
Publisher's official website: Cooperating platforms such as Elsevier and Springer provide paid access or institutional subscription downloads for some documents.
LinkOut extended resources: Jump to related resources such as institutional library collections, clinical trial databases (ClinicalTrials.gov), and genetic databases (GenBank).
Open access filtering: Use the “Free full text” filter on the left to quickly locate free full text, or visit the PubMed open access journal list for more resources.
4. Multi-language support and user experience optimization
Interface language switching: supports more than 10 languages such as English, Chinese, and Spanish, which can be set at the bottom of the page.
Mobile Adaptation: The responsive design automatically optimizes the display of mobile phones and tablets, and supports offline access to saved literature abstracts.
Visualization tools: Some documents provide chart previews (such as gene expression maps) and integrate online dictionaries (such as the "New Dictionary of All Medicines"). Double-click a word to view the translation.
PubMedpage versionImportant updates and improvements
1. Data consistency and API upgrade
Starting from December 2025, the data distributed by PubMed through FTP will be generated using the same technology as the official website and API, ensuring complete synchronization of data from each channel and improving the reliability of batch downloads and secondary development.
2. Enhanced sharing function
Email customization: After linking to a My NCBI account, you can edit the email subject and body content, and directly share search results or single document links, and the email will only be sent to the account-bound email address to enhance security.
Social platform integration: Added buttons to share directly to academic social platforms such as ResearchGate and Twitter to facilitate the dissemination of research results.
3. Visualization of search results
Added "Cited by" and "Similar articles" modules to the literature list page to visually display the citation status of literature and related research context, and assist in quickly locating high-impact papers and research hotspots.
4. Expansion of open access resources
Cooperating with more open access journals (such as AME's 36 journals included in WOS), the proportion of free full-text will be increased to 28% in 2025, and a new "OA Journal Navigation" entrance will be added to support filtering by subject and impact factor.
PubMedpage versionUsage scenarios and best practices
1. Research on scientific research literature
Quick novelty search: Set the time range (such as "2023-2025") and document type (such as "Review") through "Advanced Search" to obtain field reviews and the latest developments.
Precise positioning: Combine MeSH words and Boolean logic, such as "(neurodegenerative diseases (MeSH)) AND (genetic factors (MeSH)) AND (2024-2025 (pdat))" to lock in a specific direction for research.
2. Clinical decision support
Evidence-based medicine: Use the "Clinical Queries" module to screen literature by treatment, diagnosis, etiology, etc., and select the "High specificity" mode to obtain high-quality studies (such as randomized controlled trials).
Drug information query: Click the “LinkOut” link in the literature to go to Drugs@FDA or Micromedex to obtain detailed data on drug indications, side effects, etc.
3. Teaching and Learning
Medical Education Resources: Link to MedlinePlus through “Consumer Health” for easy-to-understand patient education materials suitable for medical student teaching and doctor-patient communication.
Literature reading assistance: Use the “Translate for Zotero” plug-in to translate literature titles and abstracts in real time, or generate AI summaries and Q&A through third-party tools such as PubMed.ai.
PubMedpage versionNotes and resource expansion
1. Data accuracy verification
PubMed only provides literature citations and abstracts, and the full text content is the responsibility of the publisher or PMC. If you discover data errors, you can submit a correction request through NCBI's feedback form.
2. Copyright and Compliance
Paid literature acquisition: Obtain paid full text through the institutional library or legal channels (such as PubMed.ai’s “Library Delivery” function), and avoid using unauthorized third-party platforms (such as Sci-Hub).
Open access copyright agreement: When citing PMC documents, you must comply with copyright agreements such as CC BY. Some journals require the original source and author to be indicated.
3. Recommendation of third-party tools
Document management: Zotero (free and open source) supports one-click crawling of PubMed documents and automatically generates references, while Mendeley (free + paid) provides team collaboration and reading statistics functions.
AI-assisted analysis: PubMed Pro (unofficial) integrates the DeepSeek large model to analyze literature trends and generate research hypotheses; PubMed.ai supports natural language questions and literature content dialogue.
