  2. About CISTI

  3. Making collection decisions based on usage • More recent collection studies on ILL/Document Delivery usage done using monograph data • Few studies looked both at serial usage AND serial gaps using ILL data as this study did.

  4. 2004 CISTI Collection Review - Usage Study • Key goals: • Assess CISTI’s serial collection strengths and weaknesses given recent budget constraints • Assess client need based on usage • Starting assumptions: • Collection met the core STM needs of clients • Emerging gaps developing in medical and business literature

  5. Scope • Analyzed usage of current serials using Document Delivery order data • Analyzed unfilled serial orders for reason of “not held “

  6. Current serials analysis • Gathered subject and bibliographic information on 8,666 serial titles • Gathered usage data on these titles based: • sample of 309,748 orders placed in 2003 • usage of the 3 main user groups (NRC staff, Canadians, international clients)

  7. Findings – Titles by Subject

  8. Findings – Filled orders by subject and user group

  9. Collection Gap Analysis • Traditional ILL study of unfilled orders cancelled for reason of “not held “ • Sample of 6,171 orders of top unfilled 318 serial titles, those with >10 hits from 2003 to 2004 • Gathered subject, bibliographic and cost information on the 318 titles

  10. Findings – "Not Held" orders by subject and user group

  11. Client validation to action • Groups telling CISTI there were collection gaps: • Canadian health library community • National Library of Medicine • NRC staff • Closing the gap • 135 more medical and health serial titles purchased • Collection Policy changed to allow for more medical and business literature

  12. Best practices • Goals met and assumptions validated • Unique study successfully evaluated both collection strengths and weaknesses • Balancing client need with subject depth • Reusable method of evaluating the collection
