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

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

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

Total Request Volume by Fiscal Year

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
