9. Cost-Per-Use: Annual Subscription Cost ÷ Annual Use

10. Cost-Per-Use: A powerful tool for assessing return on investment.

11. Cost-Per-Use: A powerful tool for assessing return on investment. But are we using CPU data to its fullest potential?

12. Chuck Hamaker’s idea: A cross- institutional analysis of CPU data &

16. Caveat: The coverage ranges for cost and use data didn’t always overlap completely.

17. Caveat: Institution-by- institution access sometimes differed for resources.

18. Caveat: The coverage ranges for cost and use data didn’t always overlap completely. Caveat: Institution-by- institution access sometimes differed for resources. Caveat: Not all sources of use data were COUNTER compliant.

19. Caveat: The coverage range for cost and use data didn’t always overlap completely. Caveat: Institution-by- institution access sometimes differed for resources. Caveat: Not all sources of use data were COUNTER compliant. We can’t really use this study’s results to make sweeping conclusions.
