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

Breakdown of Ultra-High-Use Title Request by Format


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.


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
