  1. The PubMed ID and Entrez, PubMed and PubMed Central Edwin Sequeira National Center for Biotechnology Information June 21, 2000

  2. National Center for Biotechnology Information • Created by Public Law 100-607 in 1988 as part of National Library of Medicine at NIH to: • Create automated systems for knowledge about molecular biology, biochemistry, and genetics. • Perform research into advanced methods of analyzing and interpreting molecular biology data. • Enable biotechnology researchers and medical care personnel to use the systems and methods developed.

  3. PubMed And Friends • MEDLINE • Citations to Articles in 4,000 Biomedical Journals Selected by an Expert Panel • Subject Specialists Add NLM’s Medical Subject Headings (MeSH) to Each Citation • PubMed • MEDLINE Database Plus Supplementary Material From Some MEDLINE Journals • A Component of a Larger Retrieval System, Entrez • Entrez • Integrates Access to Biomedical Literature and a Collection of Molecular Biology Databases

  4. From There to Here PubMed Daily Averages: Over 120,000 Users, 800,000 Searches PubMed has full MEDLINE With Links to Publishers Entrez Links MEDLINE Subset to Sequence Databases MEDLINE on the Web PC-based Front-End to MEDLINE MEDLINE Via TTY Early 70s Mid 80s Early 90s Mid 90s 1999 1997 2000

  5. PubMed Growth: 1997 - 2000

  6. More Friends Of PubMed • PubRef • Extends Pubmed Database to All Scientific Fields, Without NLM Indexing and Quality Control • Requested by U.S. National Academy of Sciences on Behalf of Some Scientific Journal Publishers • PubMed Central • Free Access to Full Text of Life Science Research Articles and Supporting Data • Citations to Articles Are Included in Pubmed Database

  7. Link To Related Articles

  8. Link to Books

  9. PubMed Linking Entrez Entrez Related Articles Related Sequences, Structures, Genomes, etc. PM ID GI PM ID PM ID PubMed Citation or Abstract PM ID Internal ID Related Book Sections Entrez

  10. Linking Within Entrez • Links to Related Articles, Sequences and Genome Data, and Books – Computed Automatically • Quality of Linking Improves As Database Grows • List of Related Articles (or Sequences) Is Keyed to Unique Identifier (PM ID) of Originating Citation • Similar Linking From Sequence Databases • Link to Books: PM ID  Abstract With Links Book Index

  11. Direct Link To Publisher

  12. Library-Specific Linking

  13. Other LinkOut Resources

  14. LinkOut to Other Resources

  15. LinkOut • Supports One to Many, Many to One: • Separate Links to Different Versions of an Article, e.g., HTML and PDF • Multiple Providers and Resources for a Single Citation • One External Resource Linked to One or More PM IDs (Static List or PubMed Query) • Provider Defines Holdings and Rule for Creating Link to Specific Resource • Link Rule = URL Base + Unique ID for Resource • Resource UID = PM ID or other ID Data From Source PubMed Record • Similar Links From Other Entrez Databases

  16. More LinkOut • A Library May Define Its Holdings (Online Journal Subscriptions) in PubMed • ‘One Click’ Link Through From Any Outside Site to the LinkOut Provider For a PubMed/Entrez Item
