  1. Retrieval Rate at Avery Library: Choices Zack Lane ReCAP Coordinator 7/14/2010

  2. Agenda • Last time (February 2010) we discussed general statistics for Avery Library collections • Staff wanted more detail about retrieval and retrieval rate • This presentation will focus on retrieval rate • And…will introduce Avery/ReCAP website

  3. Basic Questions Many are the same as last time: • What is retrieval rate? • What can we learn from retrieval data? • What choices can be made practically, economically? • What data are available to look at?

  4. Retrieval Rate • Retrieval rate is a measure of collection use • Target retrieval rate is 2.00% • Percentage of ReCAP collections retrieved during a twelve-month period (Calendar or FY) • One technique to gauge overall use • Important factor for ReCAP facility staffing model

  5. Avery Library Retrieval Rate is 3.37% • Yikes • Data double checked • Method calculates how long every item has been at ReCAP • CUL (not ReCAP) data used • Compare to similar data sets for other department libraries: • East Asian: 461,665 / 48,074 / 1.83% • Avery: 197,306 / 38,747 / 3.37% • BMC: 8,650 / 1,214 / 14.0%

  6. System-wide • Recent discussion about retrieval rate system-wide • Presentation at Collection Steering Committee, CUL's Increasing Retrieval Rate, 6/9/10 • It is a complicated issue; options discussed • Point of focus was retrieval rate by publication date and language

  7. The Issue • Growing concern about the retrieval rate of ReCAP collections • Retrieval volume constantly, consistently grows • Retrieval rate has also grown • Billing model at ReCAP now based on “activity units” • More retrieval = more cost

  8. Paths to Lower Retrieval Rate • Do not transfer high-use or potential high-use material • Return high-use items to onsite shelving • Limit patron access • Each option has benefits, consequences and complications

  9. Core of Discussion

  10. Avery Data • Monographs only • CLIO locations: off,ave off,fax and off,war • Focus on last 20 years of publication for retrieval rate • Focus on top-10 held (non-CJK) languages • Environmental scan of all Avery accessions • Bonus: Call number analysis

  11. Pub Date Distribution

  12. Top 10 Languages by Pub Date

  13. Primary Western Euro Langs

  14. Hard Data For English

  15. Complications with Call Number Analysis • Monographs only • Top 10 languages • Only off,ave and off,fax • LC call numbers (unclear which were proper Avery call numbers) • Best viewpoint is proportional, how they compare to each other

  16. Call Number

  17. High Use Titles • Serials vs monographs • Single-vol vs Multi-vol monograph • Subject: in scope? • ILL/BD usage

  18. Courses of Action • Standing meetings with Avery staff: weekly or bi-weekly • Meetings can address any ReCAP-topic • Develop Avery/ReCAP website; provide data directly to staff • Track results of changes
