PubMed: What is it?• PubMed is the publically available
interface used to search MEDLINE• MEDLINE
– Contains over 22 million bibliographic citation records– Covers all specialties of clinical medicine, public health,
nursing, veterinary medicine, allied health and some basic biosciences
– Coverage from1950 - present– Primarily citations from scholarly journals
• Small percentage from in-scope newspapers, magazines and newsletters
– 5,200 worldwide journals in 37 languages
PubMed• PubMed is the free, web-based
interface to MEDLINE database…BUT• It is an abstract database – only
searches the abstract and not the full text
• Get to PubMed via library links to see Find It menu to connect to full-text
PubMed Search• Default way PubMed searches is to look for your
search term as a keyword, which looks for the word in the title, abstract, and subject headings• Need to be aware of alternate terminology
when searching using keywords• Searching using MeSH (Medical Subject
Headings) uses a controlled vocabulary• Eliminates need for synonyms or variant
spellings• Can use a combination of keywords and MeSH
headings when searching PubMed
Organize Your Search Topic• Write down your topic as a statement
or question
• “Chunk” out your concepts and search each concept separately
Search Tips• Add concepts one at a time -- this gives
maximum flexibility later to combine concepts
• Use Boolean Operators (AND - OR)– The more concepts you AND together the
fewer results you will receive– The more concepts you OR together, the
more results you will receive– Boolean Operator Cheat Sheet: – www.hsl.lib.umn.edu/biomed/help/boolean-operator
s• Use the Advanced Search link to
combine sets
Search Tips• Use “*” as truncation symbol• Too many results? Try using “Limits”• Too few results? Think broadly,
brainstorm synonyms • Create an account in myNCBI to save
searches and citations for long term storage and to set up an email auto-alert to stay current on research interests
Google Scholar• Advantages
– Easy search interface– Searches across disciplines and sources – Searches full text of articles
Google Scholar• Disadvantages
– Don’t know exactly what it is searching– Searching is by exact word match only –no
subject headings to provide context– Only basic limits available – no age groups– Can’t combine sets, save searches, or send
more than 1 citation/per time to RefWorks
Google Scholar• Great tool – but use it as a
supplement to, and not a replacement for subject indexes
• Search tips– Use the Advanced search feature– Use quotation marks around phrases– Search with alternate terminology, using
parenthesis and OR (“high blood pressure” OR hypertension)
Google Scholar: Result Comparison
Combine Terminology
Google Scholar• Remember to ALWAYS access
through the Bio-Medical Library, or set your preferences in Google Scholar to indicate you are affiliated with the University of Minnesota. This will allow FindIt links and RefWorks export links to appear in your results.
