A better way to analyze your big deals

Unsub is a data dashboard that helps libraries reassess the value of their big deal subscriptions. Using Unsub, libraries can forecast their spending and fulfillment over the next five years, modeling a variety of different subscription and cancellation scenarios.

Unsub’s data-driven forecast model is customized to each institution, using their unique access, citation, and authorship patterns. To generate a 360-degree picture of access and costs over time, Unsub accounts for the effect of open access, post-termination access, interlibrary loan, journal readership decay curves, and more.

Unsub currently supports the five biggest publishers with more coming soon.
