Impactstory is an open-source, web-based tool that helps researchers explore and share the diverse impacts of all their research products—from traditional ones like journal articles, to emerging products like blog posts, datasets, and software. By helping researchers tell data-driven stories about their impacts, it's helping to build a new scholarly reward system that values and encourages web-native scholarship. Impactstory is funded by the National Science Foundation and the Alfred P. Sloan Foundation and incorporated as a 501(c)(3) nonprofit corporation.
