Circulation Data: Social Work Library

Circulation Data: Social Work Library Zack Lane ReCAP Coordinator July 2012 ReCAP Columbia University

Social Work Circulation Data • Looks at Social Work Library circulation activity • Is only one measure of collection usage • Presents data both SW specific and system-wide • ?CircDesk uses several happening locations: Social Work, Butler, BorrowDirect, HSL • No circulation data for non-circulating collections ReCAP Columbia University

?SW Library Background • ?Social Work Library became independent entity in August 2004 • ?Opening of new Social Work building • ?Print collection was previously part of Lehman Library in SIPA • ?Transition period between August 2004 and May 2005 • ?Two happening locations: • Social Work Circ. Deck • SW Circulation Desk ReCAP Columbia University

SW Library Happening Location • Data collated by happening location • Social Work Library became independent entity in August 2004 • Five primary types of circulation activity: charge, discharge, renewal, recall and hold • Most renewals and recalls are done in the OPAC happening location, dynamically by patrons themselves • Note: circulation data includes primarily “on campus” collections ReCAP Columbia University

ReCAP Columbia University

Observations • Total volume of charges has fluctuated • System-wide there has been a 27.4% decline • Volume of discharge predictably mirrors charges • Other types of circulation activity happen in much lower volume • Majority of renewals occur in the OPAC happening location ReCAP Columbia University

SW Circulation by Patron Group • Almost 3/4 of all charges are to graduate students • Patron Group definitions have changed: • Adjunct faculty, in 2008 grad students were given primary group OFF instead of GRD • Pie charts break down data for FY12 only • Bar chart compares patron group charges for each fiscal year ReCAP Columbia University

Circ Activity by Collection • Over the life of SW, charge activity is split evenly between stacks and reserves collections • In FY12, activity was heavier with Reserves • Charges to SW Stacks has declined steadily each fiscal year • Offsite charges should be placed in the Butler Happening Location • Data unavailable for non-circulating collections ReCAP Columbia University

Collection Use by Patron Group • Data for all transactions in the SW Happening Location • Nearly 80% is for the LC Stacks collection alone • Offsite charges are placed in the Butler Happening Location • Data unavailable for non-circulating collections ReCAP Columbia University

System-wide Circulation Data • System-wide circulation statistics are available for both on campus and offsite collections • Circulation data are accessible to all staff • Offsite collections can be identified by CLIO location format off,xxx. • System-wide data is available from July 2003, the date of Ex Libris Voyager implementation ReCAP Columbia University

On Campus vs. Offsite Charges • Comparison of on campus and offsite collection charges by volume • On campus charge volume declined by 27.4%between FY04 and FY12 • On campus charges have declined every year since FY04 • Offsite charge volume increased 121.3% between FY04 and FY12 • N.B. On campus collection size declines each year; offsite collections grow each year ReCAP Columbia University

Monthly Onsite vs. Offsite Charges • Monthly charges of both onsite and off-site collections are in phase with the academic calendar • Peaks in the middle of Fall and Spring terms • The pattern of offsite charges is more apparent when viewed alone ReCAP Columbia University

On Campus vs. Offsite Charges • On campu and offsite charges can be compared using a ratio • The ratio of offsite to on campus increased from FY04 to FY012 • Offsite collections are accounting for proportionally more activity ReCAP Columbia University

Charges vs. Renewals • Chart compares total volume of charges to renewals for Offsite 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 ReCAP Columbia University

More Data Available • More information about data sets can be found on the ReCAP Data Center website • Primary data categories include: accession, retrieval, delivery and circulation • Tailored data sets and analysis will be provided to staff via the ReCAP Coordinator • Please see the main ReCAP website for general information about CUL procedures and systems ReCAP Columbia University
