PubMed Database

Overview

PubMed is the U.S. National Library of Medicine's database providing free access to 36M+ biomedical citations from MEDLINE and life sciences journals. This skill covers programmatic access via the E-utilities REST API and advanced search query construction using Boolean operators, MeSH terms, and field tags.

When to Use

• Searching biomedical literature with structured Boolean/MeSH queries
• Building automated literature monitoring or extraction pipelines
• Conducting systematic literature reviews or meta-analyses
• Retrieving article metadata, abstracts, or citation information by PMID/DOI
• Finding related articles or exploring citation networks programmatically
• Batch processing large sets of PubMed records
• For Python-native PubMed access, prefer BioPython (Bio.Entrez) — this skill covers direct REST API usage
• For broader academic search (non-biomedical), use OpenAlex or Semantic Scholar APIs
