  • Accessible worldwide at no charge

  • PubMed includes:

    • MEDLINE (1966 to present)

    • Ages

  • These limits are assigned prior to indexing:

    • All Subsets (except MEDLINE)


What s new automatic term mapping change

What’s New? Automatic Term Mapping Change


Atm tips

ATM Tips

  • Details, Details, Details!

  • Modify the Query Translation box

  • Use Boolean operators: AND OR NOT

  • Use search tags

  • Use MeSH Database

  • Use Advanced Search


Advanced search try it

Advanced Search -- Try It!

  • Single Citation Matcher will be discontinued

    • Use Advanced Search box (Citation Sensor)

    • Use field searching

  • Limits, Preview/Index, History, Clipboard, Details will move

    • Links in Advanced Search


What s new citation sensor

What’s New? Citation Sensor

GOOD!

BAD!


New summary display

New Summary Display

  • No icons

    • Replaced with links to PMC and/or publisher

  • Article title and author fields

    • Positions flipped

    • Clickable link now article title, not author names

  • Related Articles link moved


Discovery tools

Discovery Tools

Goal: Serendipitous searching

  • Recent Activity

  • Free full text in PubMed Central

  • Patient Drug Information

  • Drug Sensor

  • Related Reviews


Myncbi redesign

MyNCBI Redesign

  • New look and navigation

  • New features

    • Username retrieval

    • My Bibliography


Changes to mesh

Changes to MeSH

  • New MeSH terms

    • Evidence-Based Dentistry

    • Evidence-Based Nursing

    • Evidence-Based Practice

    • Integrative Medicine

  • New age check tag: Young Adult

    • 19-24 (U.S. Census definition)

  • Summary of changes: http://www.nlm.nih.gov/pubs/techbull/nd08/nd08_medline_data_changes_2009.html


Mesh database

MeSH Database

  • Search with MeSH terms (Headings, Subheadings, Publication Types); Supplementary Concept terms (Substance Names); Pharmacological Action terms

  • See scope note and other helpful information

  • Display MeSH terms in the hierarchy

  • Limit MeSH terms to a major concept

  • Attach subheadings

  • Link to NLM MeSH Browser


Floating a subheading

Floating a Subheading

  • Definition: Search for a subheading without attaching it to a particular MeSH heading

  • Goal: Broader retrieval (but less precision)

  • Examples

    • Not sure which drug should be used for therapy? /tu

    • Not sure which drug caused the adverse effect? /ae

    • The subheading aspect is of interest, but it is not associated with the searched MeSH term

    • Indirect questions: What conditions does smoking affect?


Searching with field tags

Searching with Field Tags

  • Affiliation [AD]

    • Institutional affiliation and address of the first author of the article

    • Be creative/comprehensive: Institution name; endowed name; abbreviations; zip code; e-mail suffix

  • Journal Name [TA]

    • All single-word journal titles should be tagged

  • Personal Name as Subject [PS]


Searching with field tags continued

Searching with Field Tags (continued)

  • MeSH Headings [MH]

    • Major MeSH [majr]

    • To turn off auto-explode

      • [mh:noexp]

      • [majr:noexp]

  • Subset [SB]

    • LinkOut provider: loprovmedlib [sb]


Searching with field tags continued1

Searching with Field Tags (continued)

  • Journal subsets

    • Bioethics journals: jsubsete

    • Health administration journals, non-Index Medicus: jsubseth

    • Index Medicus journals: jsubsetim

    • Consumer health journals, non-Index Medicus: jsubsetk

    • Health technology assessment journals: jsubsett


Other search types

Other Search Types

  • Clinical Queries

    • Evidence-based medicine hedges
