  1. 60 Years of Measuring the Use of Information and its Sources:From Consultation to ApplicationbyDonald O. CaseUniversity of Kentucky, USA LIDA 2014

  2. • 3 Eras of User Studies • Observing Outcomes • Trends in Studying Use • Why Outcomes Matter History of Observing Use, Effects and Outcomes

  3. The Collection The Document The Chunk The 3 Eras Case LIDA

  4. Identifying Origins: Some General Comments Three Eras

  5. 1836-1935: Collections 1936-1958: Documents 1959-Now: Chunks The 3 Eras Case LIDA

  6. The Era of Collections • Long Essential to Library Management & Assessment • Breakdown of Collection Use • Collection/Services as Focus

  7. The Era of Documents • What Book/Magazine/ Paper do Users Prefer, & Why? • Rare: What Happens as a Result? Outcomes of Exposure • Shift to Qualitative Methods

  8. The Era of Chunks • Units of Information Smaller than a Document, e.g., an Answer • More Emphasis on Outcomes, e.g., Awareness or Tasks • Scientists, Engineers, Managers

  9. What is “Use”? • An Ambiguous Word Use and Outcomes

  10. What is “Use”? • An Ambiguous Word • Limited Observations Use and Outcomes

  11. What is “Use”? • An Ambiguous Word • Limited Observations • Effects or Applications Rarely Measured in Past Use and Outcomes

  12. What is “Use”? • An Ambiguous Word • Limited Observations • Effects or Application Rarely Measured in Past • But More Common Now Use and Outcomes

  13. QUANTITATIVE MEASURES, e.g., • Yes-No Responses to Items like “I learned something new” or “I was reassured.” • Scalar Responses to Statements like “I tried to relate what I read to my own experience.” QUALITATIVE QUOTATIONS, e.g., • “What she told me made me feel better.” RESEARCHER SUMMARIES, e.g., • “The student’s essay showed how she had paraphrased the material she read.” What We Looked For

  14. Study Results

  15. Need  Seeking  Finding  Use Potential Explanations

  16. THEN: Need  Seeking  Finding  Use NOW: Need Seeking Finding Use Outcome Potential Explanations

  17. Observing Outcomes is Difficult Qualitative Methods are Better-Suited They were Not Popular Until the 1980s Potential Explanations

  18. Another Potential Explanation: Pressure from External Environment • Parent/Funding Agencies of Libraries Want Better Results and Justifications Potential Explanations

  19. Pressure from External Environment • Parent/Funding Agencies of Libraries Want Better Results and Justifications • LIS Scholars Face Similar Pressure, Plus Competition from Other Disciplines Potential Explanations

  20. Conclusions • Assessing Outcomes is Important • May Require In-Depth Methods • Quantitative Measures Also Useful • Yet Such Measures also have Limits Final Point

  21. Thank You for Listening! Hvala! Coffee, Anyone?
