  • 1. Extended search techniques for health librarians: from grey lit to snowballing What kinds of ’expert search’ skills emerge from the above illustration? Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 2. Tonight’s class topics & activities: Health librarians as expert searchers ‘Extended search techniques’ Evidence-based practice(s) Grey literature searching Search assignment(s) Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 3. Reflective exercise – Take 5-7 mins. Some questions to consider re: search assignment I: • What did you learn after you completed the search assignment? • What would you change or do differently? • What surprised you about biomedical searching – and the databases? • What did you learn about searching? • 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 2012
  • 4. Extending your search“…while MEDLINE is considered the premier source for accessing medical information, it has been established that searching MEDLINE alone generally fails to identify allpossible studies for inclusion in systematic reviews … a number of guidelines have beenproduced 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…” 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. Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012

  • 8. Do expert search skills save lives? Johns Hopkins’ clinical trial volunteer Ellen Roche died in 2001 after she participated in a clinical trial for a proposed asthma treatment... Were health librarians consulted for this trial? Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 9. What is “grey” about grey literature?"information produced on all levels of government, academia, business and industry in electronic and print formats not controlled by commercial publishing" ICGL Luxembourg definition, 1997 - Expanded in New York, 2004“…a body of materials [not] found easily through conventional channels such as publishers … frequently original and usually recent“ Wikipedia entry on ‘gray literature’ Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012

  • 11. Different types of grey literature• Theses & dissertations• Conference proceedings• Newsletters• Reports• Government documents (including NGOs, IGOs)• Informal communication (telephone calls, meetings)• Translations• Census, economic & other data• Conference proceedings & abstracts• Research reports (completed & uncompleted)• Technical reports, standards, patents• Videos• Clinical trials & practice guidelines Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 12. Newer sources/types of grey lit & data• e-prints, preprints, post-prints• emails, blogposts, even tweets on Twitter• web 2.0 communication channels• wiki articles & virtual worlds like Second Life• listserv archives• digital libraries (i.e. Institutional Repositories)• grey (gray) data; spatial data (ie. Google Earth)• meta-searching, federated searching, portals• electronic & social networks / images, maps• DOCLINE & other interlibrary loan networks Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012

  • 15. Impact in medicineAlthough not always considered scholarly, grey literature is produced by experts … and “serves scholars and lay readers alike with research summaries, facts, statistics, and other data that offer a more comprehensive view of the topic of interest.” Outten, C. Gray Literature. 2008 • Medline is not enough… • Grey literature opens doors -- fills in ‘evidence’ gaps • Accessible on the open web via Google for free • Outside mainstream scholarship & research; unconventional format • Data-mining - think of hospital patient & epidemiological data Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 16. Expert search skills for health librarians• Assume expert roles in biomedical database searching• Describe expert role(s) assumed by health librarians in evidence-based practice• Knowledge of teaching, learning styles and strategies• Learn how to use pre-appraised sources such as Cochrane and UpToDate• Be able to search the grey literature using Google, Scirus & web search tools• Understand systematic review process; methodologies & statistics• Articulate five (5) steps of evidence-based clinical practice• Understand hierarchies of evidence to search filtered / unfiltered• Search by clinical domain ie. diagnosis, etiology, prognosis, therapy• Engage in critical appraisal & reflective practice See Top Ten Competencies in Medical Reference, 2012 Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
  • 17. Expert strategies • Document searches fully; ask for help from peers • Network with GL producers; modify your strategies as needed • Import citations into RefWorks or Mendeley • Watch scholarly publishing trends; copyright & ‘self-archiving’ • Identify relevant organizations to search NYAM list of greylit producershttp://www.nlm.nih.gov/hsrproj/ Dean Giustini, SLAIS Adjunct faculty, LIBR534 March 2012
