17. “ What is the most

20. A Medline Record
Indexing Status:
This describes whether
the record has been fully
indexed by the National
Library of Medicine.
21. A Medline Record
Authors / Title:
Self-explanatory. Author
names are hyperlinked so
you can see other papers
written by each author.
23. A Medline Record
Medical Subject Headings:
Tags applied by librarians at
NLM to make it easier to find
articles. More to come…
24. The 5 principles of online searching
1. Define your question and break it down
into its separate concepts.
2. Search each concept separately.
3. Combine search terms (AND/OR).
4. Apply limits.
5. Evaluate your results and modify your
search strategy if necessary.
28. Database Searching
Databases can be searched in 2 ways:
► Using subject headings
Easier to search and leads to more
relevant results.
► Keyword / Text word searching
Harder to search as you have to think of
every possible synonyms for each concept.
Usually gives less relevant results.
29. Why bother with MeSH?
cancer
tumor(s) There
are
tumour(s) Neoplasms/ 25,588
MeSH
neoplasm(s)
terms
neoplastic
30. Another MeSH example…
poverty financial
social disparity distress
poor extreme need
Poverty/
breadline social inequity
financially low income
disadvantaged destitute
34. Boolean Operators: AND/OR
AND directs the computer to
search for every reference that
contains all of the search terms
specified. Each term must be
present in every reference.
OR = tells the computer to
retrieve every reference that has
at least one of the search terms--
all terms do not have to be
present in every reference.
36. Limiting your search
Age groups Publication date
► Neonates, babies ► Last 5 years
► Elderly people ► From 1990 –
Languages Publication Type
► English only ► Systematic Reviews
► French, German… ► Case histories
37. Defining our question
How effective is ozone
therapy for treating
dental caries?
Limit to review
articles published in
the last 5 years.

39. “ I am not
discouraged, because
every wrong attempt
”
discarded
is a step forward.
Thomas Edison
40. Now have a go yourselves…
What can I do
to alleviate
dental anxiety in
my child patients?
41. Summary
Identify the individual concepts of your
topic
► Select the database(s) to search.
Search one term or concept at a time.
► Use the “Suggest subject term” feature if available
► Use the Explode feature to search all narrower terms
Combine your concepts
► Use OR to combine terms that represent the
same concept. OR increases retrieval.
► Use AND to combine terms that represent
different concepts. AND decreases retrieval.
42. Summary cont’d…
Apply any limits you need
► e.g. Language, dates, age groups, publication types.
Evaluate your results
► And don’t be afraid to modify your strategy and
start over if necessary
► To get your articles, look for the icon to
download or to locate it in the library
► …and don’t forget that we have an ILL service if you
need an article or book that we don’t have

45. The 20-minute rule
If you have not found
what you are looking
within 20 minutes…
…it’s time to call me!
However, I will ask you to
show me the research you
have done to date!
So, our first question… (read question). How would you go about looking for the answer to this?
Show a Medline citation here…Different parts of the record. Get them to click on Find citation and then to type “Evolution of human teeth and jaws…”
Show a Medline citation here…Different parts of the record
Show a Medline citation here…Different parts of the record
Show a Medline citation here…Different parts of the record
Before searching MEDLINE or any other article index (a.k.a. database), the first step is to define your question and break it down into its separate concepts. Breaking down your question will help you to identify the subject headings in Medline that are used to describe articles about your topic.
There are 5 principles of online searching…Before searching MEDLINE or any other article index (a.k.a. database), the first step is to define your question and break it down into its separate concepts. Breaking down your question will help you to identify the subject headings in Medline that are used to describe articles about your topic.
This is different to Google where we just type in our search question. In databases, we search concepts separately.During this section will introduce searching concepts separately, MeSH, keywords, and then log in to MEDLINE and search for our concepts separately.
Why use MeSH?MESHPreferred list of terms used by the National Library of Medicine to index each article added to Medline / PubMedProvides a “controlled“ or consistent way of retrieving information that may use different terminology for the same concept. Indexers assign the most specific subject heading available, thus yielding more precise resultsKeywordsSearch title and abstract for the exact word or words you typeIn MEDLINE, keywords do NOT search full text of articleSearch article titles and abstracts to develop list of synonymsSearch for “cancer” and see what happens
Imagine having to use all of these synonyms in a search! MeSH makes your life easier…Before next slide – get them to do their first search in Medline – find the subject heading for dental caries.
Do I search for tooth decay? Dental caries? Dental decay?Explode “dental caries” to search ALL terms indented belowFocus your search to those documents in which your subject heading is considered the major point or focus of the article.
Will talk about AND/OR later, but for now this is a way of combining our terms to get exactly what we want.
Limits allow us to reduce the number of articles and only give us what we really want. So if we are only interested in elderly people, in articles in English or French, or published in the last 5 years, this is how.
And then show how to limit results in Medline. One limit at a time is best.
Evaluate your results, and be prepared to modify and repeat if necessary
