From Lisa Hinchliffe’s Scholarly Kitchen’s Q & A with the co-founders of Unsub:

Unsub is a tool that helps librarians analyze and optimize their serials subscriptions; it’s like cost-per-use (CPU) analysis on steroids. Using Unsub, librarians can get better value for their shrinking subscription dollar — often by replacing expensive, leaky Big Deals with smaller, more custom collections of a-la-carte titles.

And:

We’ve received off-the-record feedback from several publishers amounting to this: “Unsub is going to kill our subscription model…thanks! We’ve wanted to flip, but haven’t had the courage yet.”

I’m heating up my popcorn.
