  2. Findings: Requests • Request volume grew each year from the opening of ReCAP until FY09 • Since FY09 the total has grown very slowly • Impact of mass digitization is unknown • Monthly requests are in phase with the academic calendar • Net decline from busy to slow months is approximately 33% • Collections are increasingly renewed • Average user requests follow 80/20 rule ReCAP Columbia University

  3. Request Data • The terms request and retrieval are used interchangeably in most ReCAP documentation • ReCAP tracks retrievals; CUL tracks requests • There is not a one-to-one correspondence • Majority of data corresponds • Since granular data is available only for requests, ReCAP Coordinator uses it for analysis ReCAP Columbia University

  4. Request Data: Granularity • Barcode • Delivery Location • Default Delivery Location • Date • Time • Type • Patron Group • Bib ID • UNI • Hashed UNI • Format • Publishing Date • Language • Title • Holdings ID • Call Number • Enumeration/Chronology • Item ID • CLIO Location • Fiscal Year ReCAP Columbia University

  5. Request Data • 443,311 total requests since ReCAP opened • FY08 : 59,755 • FY09 : 69,060 • FY10 : 71,119 • FY11 : 71,513 • Includes both patron and staff requests • Excludes many staff requests • Represents only CUL activity at the ReCAP facility • Patron access to offsite collections is excellent: dynamic with few failures ReCAP Columbia University

  6. Charts ReCAP Columbia University

  7. Total Volume by Fiscal Year • Every year CUL accessions more collections at ReCAP • With more collections at ReCAP, patrons have requested more items • Data does not include some staff requests and the Google Book Project • Volume did not significantly increase between FY09 and FY10 • This may be attributable to increased renewal of offsite collections ReCAP Columbia University

  9. Circulation Activity of Offsite Collections • Chart compares total volume of charges to renewals for ReCAP collections • Graduate students and Faculty request more offsite collections than Undergraduates • Graduate students and especially Faculty have higher renewal/charge ratios • Over time, these two patron groups tend to renew more than charge • CUL may expect to see steady or decreasing request volume as a result ReCAP Columbia University
