1. Discovery by the Numbers: An examination of the impact of a discovery tool through usage statisticsJody FaganDirector of Scholarly Content Systems, James MadisonUniversity, faganjc@jmu.eduMeris MandernachCollection Management Librarian, James Madison University,manderma@jmu.edu

2. What we will cover today General usage trends Discovery tool usage during the first year Changes in other database usage after discovery tool implementation Implications of usage statistics on librarycollection decisions One approach with measuring library discoverytool usage 3. Overview of James MadisonUniv. 19,000+ FTE Comprehensive university with undergrad focus part of statewide system 4.

Show me the numbers! 16. Limitations of our study Local data (circulation) confounded by changes inthe way we count things Only one year of EDS data Confounded by inconsistent vendor data andreports EBSCO COUNTER Really? ProQuest / CSA platform change Cannot assign causation to correlations 17.

Correlations, not causations:summary Use of JMU Libraries (buildings and web site) isup Catalog searching and circulation is down Discovery searching is up, and rivaling thecatalog Total full-text accesses Changing patterns from link resolver to direct fulltext access? Increase in total full-text downloads? Some EBSCO subject-specific databases are decreasing in use But have better full-text plus custom link ratio than 31. So what?!? Cancel everything because you have a discoverytool? Duplicative subject content within discovery Use of XYZ database dropped last year.. Give itthe axe! 32.

Cautions of working with usage data Identify research questions Never work alone Look at many years of data and multiple sources Remember correlation does not imply causation 34. Cautions of working with usage data Identify research questions Never work alone Look at many years of data and multiple sources Remember correlation does not imply causationWhy use data at all? Use data to plan strategically Systems decisions Organizational common ground Resource allocation 35. Future research Impact on physical collection use: requires study Get a big picture perspective of full text usage Investigate full text + custom link ratio (is this auseful metric?) Are users discovering more full text or is therejust more full text to be discovered? Instruction impact on usage 36. Questions?
