- 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.
- 22. A Medline Record Source: Information about the journal of publication and where to find the article in that journal.
- 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.
- 25. Principle #1 Define your question and break it down
- 26. Defining our question How effective is ozone therapy for treating dental caries ? 10/4/2012 McGill Library 26
- 27. Principle #2 Search each concept separately
- 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
- 31. Dental caries in MeSH Stomatognathic Diseases Tooth Diseases Tooth Demineralization Dental Caries Dental Fissures Root Caries
- 32. Defining our question How effective is ozone therapy for treating dental caries? 10/4/2012 McGill Library 32
- 33. Principle #3 Combine your search terms (AND/OR)
- 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. 10/4/2012 McGill Library 37
- 38. Principle #5 Evaluate your results
- 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 10/4/2012 McGill Library 42
- 43. “ What can I do if I need more help with literature searching ” and finding articles?
- 44. Ask your Martin Morris liaison 514 398 4475 ext 09880 librarian martin.morris@mcgill.ca Library http://www.mcgill.ca/library/ library-assistance/classes workshops Reference / Information http://www.mcgill.ca/library/ Desk library-using/branches
- 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!
- 46. Any questions?
Notas del editor
- 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
