  • Maurice Bouchard July 2, 2012
  • What is PubMed?• PubMed is a powerful search engine – Established in 1996 by NCBI at the NLM – MEDLINE, life science journals, and online books – Articles from at least 1914 to the present – Available to anyone with an Internet connection • no software installation required – EBSCO and ISI are proprietary competitors• PubMed Central – Free archive of biomedical and life science journal articles• PubMed Health – Reviews of clinical effectiveness research
  • How is PubMed used?• Simple search – Single search box for keywords • with auto-complete – Keywords combined with Boolean AND – Automatic Term Mapping • MeSH • Journals • Full author  author index • Full investigator  full investigator index • When a match is made searching stops (e.g., physiology)
  • Simple Search
  • How is PubMed used?• Advanced search – Many fields available for key word searching • Author, journal title, article title, abstract, dates, etc, etc – Choice of Boolean operators: AND, OR, NOT – Auto-complete and show index combine powerfully – Complex searches can be constructed and saved – No (practical) limit to the number of clauses – Components can be previewed, saved, and reused – Search query language can be manipulated
  • Advanced Search
  • How is PubMed used?• Results – Results are ranked by relevancy • exact match on MeSH terms come first • title matches are also highly ranked – Narrowing the search is easy • many facets available • facets are configurable • „clickable‟ date histogram – Getting full-text – Related articles – Citation list
  • Results
  • Results
  • How is PubMed used?• Other features – Send results to… • email • citation managers • file • “My Bibliography” – login required • more – Results work with Zotero – Searches can be saved – Alerts can be generated – RSS feed
  • Zotero
  • RSS Feed
  • How is PubMed used?• Other tools – Single Citation Matcher – Batch Citation Matcher • email a | [pipe] delimited list to retrieve PMIDs – Clinical Queries • limits results to clinical research areas – Topic Specific Queries • pre-built search query on a topic (e.g., cancer, ethics) – PubMed Mobile
  • Is PubMed Perfect?• Lacks capability to browse• Coverage years by journal?• No proximity searching• Facet UI is clunky• Generates queries it cannot run• Tighter integration to citation managers
  • Why PubMed?• Authoritative• Expansive coverage – 21,000,000 articles – 25,000 journals• Tight MeSH integration• Well supported with help, guides, tutorials• Free – no login required for most features – free login for other features
