Unpaywall provides a complete index of open access articles that can be used by libraries and researchers to identify content that is freely available rather than needing to be purchased through journal subscriptions. The summary analyzes data on open access availability and usage trends to forecast that 50% of article views could currently be fulfilled through open access, increasing to 70% in five years, meaning subscriptions will only be needed for 30% of content. It encourages libraries to cancel "big deal" journal subscription packages with confidence, using the Unpaywall tool and data to show alternative access options and potential cost savings over time.
