Chemicals, Drugs and Genetics Oh My!: Searching PubMed and Beyond


This specialized class will help improve your effectiveness in searching PubMed and related NLM and NIH databases for literature information on chemicals, drugs and genetics. The course begins with searching PubMed for drug information with MeSH terms, Supplementary Concept Records (SCR), and Pharmacologic Actions (PA). Additional topics include searching related databases for drug information (Week 2), searching for chemicals and with chemical nomenclature (Week 3), and locating literature related to genetics and genomics (Week 4). This course assumes a strong working knowledge of PubMed including an understanding of automatic term mapping, the importance of reviewing the Details box after searches, and using the Advanced search page and the MeSH database.


By the end of this class, attendees will be able to:

  • Understand the between MeSH terms, subheadings, Phamacologic Actions, and Supplementary Concept Records
  • Experience and understand when to use specific National Library of Medicine databases to search for chemical and drug information and literature
  • Work with literature resources related to genetic diseases and research
  • Identify related literature resources for additional learning
