From Lisa Hinchliffe's [Scholarly Kitchen's Q & A](https://scholarlykitchen.sspnet.org/2020/05/19/taking-a-big-bite-out-of-the-big-deal/) with the co-founders of [Unsub](https://get-unsub.org/):
> [Unsub](https://get-unsub.org/) 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](https://scholarlykitchen.sspnet.org/2019/03/07/value-big-deal-leakage/) 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.
