  2. 2.  Health librarians as expert searchers  ‘Extended search techniques’  Evidence-based practice(s)  Grey literature searching  Search assignment(s) Tonight’s class topics & activities: Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2017
  3. 3. Reflective exercise – Take (5 x 5) = 10 mins. Some questions to consider re: search assignments: • What did you learn after you completed the search assignments? • What would you change or do differently? • What surprised you about biomedical searching – and the databases? • What did you learn about searching? About point of care tools? • Did you learn on your own …or with your peers? • What worked for you? What didn’t? • What do you need to do to become an expert? “Reflective practice involves careful consideration of one’s experience in learning…” Donald Schoen. The Reflective Practitioner 1983. Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2017
  4. 4. Source: Helmer D et al. Evidence-based practice: extending the search to find material for the systematic review. Bull Med Libr Assoc. 2001 Oct;89(4):346-52. “…while MEDLINE is considered the premier source for accessing medical information, it has been established that searching MEDLINE alone generally fails to identify all possible studies for inclusion in systematic reviews … a number of guidelines have been produced for conducting systematic review searches that extend beyond MEDLINE … … search protocols based on these guidelines generally require that researchers and librarians search the subject-specific and specialized databases… the gray literature, handsearch key journals, scan reference lists, identify conference proceedings & consult with researchers in the topic area…” Extending your search Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2017
  5. 5. Extended search techniques • Documenting all search activities • Googling & Google scholar-ing • Search for grey (gray) lit • Identify conference proceedings • Scan reference lists & bibliographies • Contact experts in the area • Personal communication i.e., telephone calls, emails, tweets? • Blogsearching, specialized websites, directories • Search academic vitaes Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2017
