Unsub is already used by hundreds of libraries and several large consortia, even though it was only launched in November 2019.
The work that @jasonpriem & @researchremix of @unsub_org do is incredibly important -- was super helpful in understanding our alternatives and making sure we had a sound strategy in place if/when we ended up out of contract with any publisher
We have found Unsub to be a great tool in our serials review toolbox. It offers the essential data we use in review projects, and in one place for ease of use. It offers important data we were unable to effectively marshall in the past, specifically citation and authorship data, open access data, ‘instant fulfillment’ and forecasting, all for an incredibly reasonable price. The staff are quick to respond to questions or concerns, and actively seek customer feedback to continuously improve their product.
