Search for Books Rule of Thumb

• Search your host campus library online catalog
  first
• Not there? Check out the UTSPH online catalog
• If item at UTSPH, well mail it to you
• If not at UTSPH but at other TMC library, request
  through ILL at host institution
• Not at UTSPH?
• Request through ILL at host institution

Search for Journal Articles Why Ovid Medline?

• Best for expert searching
• Is it the same as PubMed?
• PubMed is a little more current (1 2 weeks)
• Ovid In-Process file
• PubMed picks up a few things not found in Ovid
• BUT
• PubMed journal links are not up to date
• You cant go from the citation to the FT

13
Five Strategies for Effective Searching

• Develop a search strategy
• Use the vocabulary appropriately
• Look at the bibliographies of the really good
  articles
• Find out who has cited the really good articles
• Ask a librarian!

14
Strategy 1 Develop a Search Strategy

• Write out your search strategy
• Combination of terms and concepts
• Three concepts generally works the best
• Search broadly for each concept, and narrow by
  combining terms 

15
Strategy Examples

• Examples
• What are the risk factors for cardiovascular
  disease among men?
• How does race and/or ethnicity affect risk for
  diabetes?
• What is the appropriate prophylactic treatments
  for a women with either the BRCA-1 or BRCA-2
  genes?

16
Conceptualize Search

• Think about synonyms or like terms to describe
  the concepts
• Risk factors
• Risk factors or lifestyle or genetic disposition
  or list other individual risk factors
• Cardiovascular disease
• Cardiovascular disease or heart attack or
  hypertension
• Men
• Men or males

17
How OR and AND work
Risk factors or lifestyle or genetic disposition
or list other individual risk factors
In this search, we have tried to find all terms
that are related to immunizations by using OR.
This gives us a very large result cluster.
18
How OR and AND work
Risk factors or lifestyle or genetic disposition
or list other individual risk factors
Cardiovascular disease or heart attack or
hypertension

Once we finish searching each concept, we need to
combine them using AND.
We want to find the articles where all 3 circles
converge.
Hispanic or Mexican American or Latinos
19
How OR and AND work
Risk factors or lifestyle or genetic disposition
or BMI or obesity or list other individual risk
factors
Cardiovascular disease or heart attack or
hypertension

Hispanic or Mexican American or Latinos
The purple combines both the health policy terms
and the country terms using AND
The orange combines both the immunization terms
and the country terms using AND
20
Strategy 2 Use the Appropriate Vocabulary
