Retrieval Rate at Avery Library: Choices

Zack Lane

ReCAP Coordinator

7/14/2010

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

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?

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

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%

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

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

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

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

High Use Titles

• Serials vs monographs

• Single-vol vs Multi-vol monograph

• Subject: in scope?

• ILL/BD usage

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
