ReCAPColumbia University


Three main categories: request, accession and circulation

Request and accession sets developed and refined 2008-2010

MS Office 2010 allows better “automation” Data flows into Excel, pivot table, pivot

charts and PowerPoint. Beginning to “standardize” system-wide

and department reports Plan to push data and analysis out


ReCAP Data Center is clearinghouse for system-wide data and analysis◦ Request rate◦ Timing of requests◦ High use titles◦ High volume requests◦ EDD◦ Publication Date (Monographs)

Department websites have both explicit data and presentations


Mining ReCAP data but also looking at system-wide and department trends

Internship project found evidence in data of:◦ Policy changes: REG loan period 4-weeks to 1 term◦ System/Procedure: BDirect loans charge to BDX◦ User behavior patterns: charge/renewal patterns

Department analysis limited to happening location

Crafting analysis will be iterative process Can interesting visuals be useful?
