  6. History of Accession • The history of CUL accessions at ReCAP can be divided into three periods: • FY01/02-FY03/04, Load In. Large-scale transfer to clear onsite backlog and at obsolete off-site facilities; 500k per year • FY04/05-FY09/FY10, Middle Phase. Continued effort to clear backlog, re-purpose library space and offset collection growth; 300k per year • FY10/11-, Restricted Phase. Slow-down a result of budget, delaying planned construction of new module; 150k per year ReCAP Columbia University

  9. Request Rate • Measure of collection use • CUL targets low-use material for transfer • Target requst rate is 2.0% per annum ReCAP Columbia University

  10. Butler Media Center • Is this number correct? • Yes, verify that items belong explicitly to BMC. CLIO location off,bmc. • What does it mean exactly? • Higher than average requests from smaller than average collection. • How can I track statistics? • BMC/ReCAP website • Can we distinguish requests by format? • DVD : 7.81% • VHS : 12.2% ReCAP Columbia University

  11. High-Use Titles • 192,433 different titles requested from ReCAP (2,063,044 titles at ReCAP) • 8,885 titles request 5 or more times since ReCAP opened • Those 8,885 titles account for 134,920 requests or 34.1% of all requests • To compare: August 2009: 6,234 titles, 95,449 requests and 33.0% of all ReCAP requests ReCAP Columbia University

  13. Ultra-High-Use Titles • An ultra-high-use title is any title that has been requested 100 or more times since accession • 136 titles accounting for 28,516 requests or 7.2% of all requests • These titles are roughly half archival collections and half serials • Print vs non-print ReCAP Columbia University

  15. High-Use Comments • Impact on service points • Physical traffic of CUL collections • Access model for patrons • Opportunities for instruction • Reduce costs • Usage patterns differ for print vs non-print, languages, publication dates, etc. ReCAP Columbia University

  16. Publication Date • Monographs : all records with format “am” • Only include complete dates 1850-2010 • Substantial holdings of monographs published between 1950 and 1990 • Post-2003 materials were transferred directly to ReCAP at the time of acquisition • Approximately 30,000 new acquisitions per year are sent directly to ReCAP • Further analysis indicates that recent publications are requested by patrons at a higher rate ReCAP Columbia University

  19. Timing of Request • CUL advertises delivery “within two business days” • ReCAP’s “business day” is defined according to the file transfer times • Business day is 6:00am-2:45pm, Monday to Friday • In this model 35.7% of requests are filled in one business day • All other requests are filled in two business days ReCAP Columbia University

  22. EDD • Physical delivery has been constantly rising as more collections are accessioned • EDD volume had been dropping per capita due to accessibility of electronic backfiles • In January 2009, Health Sciences Library began transferring serial collections • EDD volume began to rise both in aggregate and in proportion to physical delivery ReCAP Columbia University
