The problem with using cost-per use analysis to justify journal subscriptions | A Way of Happening

"In a number of cases now, subscriptions to scholarly journals that appear to be well used turn out not to be unnecessary subscriptions. What is going on here? Librarians have the usage data for these journals. The numbers! The undeniable evidence that there was a use or view! How can these be misleading? 

I don’t think there is one big problem here. I think there are lots of little ones. Altogether I think they show that we need to seriously reevaluate how we calculate cost-per use. And if there truly is a need to subscribe to some journals that have high usage counts."
